Coffee Ice Cream

Coffee Ice Cream

This is adapted from the Modernist Cuisine Coffee Creme Brulee recipe and from various ice cream recipes from the internet that are all basically the same with small variations in quantities.

Coffee Infused Cream

  • 8 oz whole, dark roast coffee beans
  • 16 fl oz Heavy Cream
  • 8 fl oz Whole Milk

Combine in a container you can close and store in the refrigerator for 24 hours.
After 24 hours, remove the coffee beans from the cream.

Notes on this step:
I used a mesh strainer and a funnel. I imagine a coffee filter would be a mess
and is totally overkill since you have whole beans not ground beans.

I have a 32oz bottle and it doesn’t quite hold all of the milk during the
infusion step because the beans take up a lot of space. I just top it up after
the beans are removed. Final weight of the cream was ~720g after bean removal
and top up.


Coffee Custard

  • 6 egg yolks
  • 2/3rds cup sugar
  • Coffee cream from above

Whisk 6 egg yolks until lightened in color.

Add sugar and cream and mix thorougly so sugar is disolved and mixture is
homogeneous.

Put custard base in vacuum bags / ziploc bags.

Sous vide at 176ºF (80.6ºC) for 1 hour.

Remove cooked custard bags from bath and refrigerate until cold or over night.

Notes on this step:
Whisking eggs took me about 5 minutes in the mixer.

We are making a custard here. The sous vide method is nice because you don’t
have to worry about your cream being too hot and curdling the egg yolk or
straining out little bits of curdled egg. Making a custard is something I am
bad at. If you don’t have an sous vide machine or immersion circulator
whatever you can make this custard the traditional way.

That would look like this:

Warm cream in a sauce pan and dissolve sugar into it.

Let cream cool to below 180ºF (82ºC). This is the temp that curdles egg yolk.

Whisk egg yolks until lightened in color.

Slowly add cream to egg yolks while stirring constantly. Which is to say,
“temper” the yolks with the warm cream.

Return to sauce pan and raise to ~175ºF (80ºC). The custard should “coat the
back of a spoon” which is nice and all but do yourself a favor and stir it
constantly and use a thermometer. If you get over about 180ºF you’ll be
enjoying scrambled ice cream.

Strain through a fine mesh strainer into a cold bowl / container.

Refrigerate until cold.


Coffee Ice Cream:

  • Coffee Custard from above.
  • Finely ground coffee (optional)
  • Vanilla Extract (optional)

Prepare ice cream churn according to directions.

Churn until the ice cream has the consistency of soft-serve. Times vary.

Move ice cream to freezer to finish. Roughly 3 hours.

Notes on this step:
If you want little flecks of coffee so people get a hint of what’s in it and
the color is a little more coffee-like you can add a small amount of finely
ground coffee.

A small amount of vanilla extract might be nice here too. Add vanilla after
all of the cooking because vanilla flavor is mostly volatile organics that can
evaporate or degrade when you cook. Might as well get as much flavor from that
extract as we can. Probably not more than 1/4 teaspoon.

My churn seems to take longer than expected and this is a small batch in the
churn which doesn’t help. Mine took almost an hour to freeze and probably
could have gone another 20 minutes. A little longer in the churn can help the
post-freezer texture.

Eclipse

There was a lunar eclipse last night and I took some not great pictures. This is a direct consequence of my not having a zoom or telephoto lens. My longest is the Canon 50mm f/1.4 which is on an APS-C crop so it’s more like an 80mm in big-boy cameras.

The telescope does a decent job of looking at things like the moon and the larger planets but mars was just an indistinct bright spot even though it is very close right now. I could have gone to the 8mm objective but a) that’s not a very good lens and b) the amount of shaking makes it hard to see anything anyway. Maybe some day I’ll get a better scope but I just don’t use the one I have enough to really justify it.

Bill and I made beer again. This one is a clone of Fuller’s London Pride which we are tentatively calling Austin Smug. The final gravity ended up almost 10 points low (1.006 vs 1.015 target) and was only 12 points with the priming sugar in. We did see something interesting during the initial brew. We got a real, good cold break which was probably facilitated by adding a coagulant Austin Homebrew recommended. I have a video of the bits and pieces settling out. Sorry for the iphone quality video.

Finally, I got a second iSi cream whipper so I can make waffles and put whipped cream on them at the same time. But as a side benefit I also have some CO2 chargers now also so I made some carbonated grapes. I have a video of those too.

Snowboarding

I’m back from my trip to Colorado. I had a great time and I’ve finally gotten to the point I can snowboard greens somewhat competently. I took my camera along and took some pictures. I’m particularly happy about the night sky ones but I think they all turned out ok.

Learning to snowboard involves a lot of sitting and then a lot of falling. For all of the time I spent on the ground only a few of them actually hurt at all. The worst one was Friday which was also the best day I had on the mountain. It was snowing, starting a little before sunrise and continuing all day. There was fairly deep powder everywhere. I had taken lessons on Sunday and Wednesday with Monday on my own just practicing on the beginner runs. Friday I went back to the long greens at the top of the mountain we visited in my Wednesday lesson. I had so much fun just doing those and learning to run downhill instead of just traversing across the hill. I had lunch and then went back up top and I was most of the way down the longest green and fell coming onto my toe side edge. I’m “goofy footed” meaning I lead with my right foot so I would have been moving to the right looking uphill and fell onto my front. My right elbow caught the snow and I got a minor pull in my right triceps as my top rotated and my bottom tried to continue to the right. It wasn’t awful but I knew I was tired and that continuing would probably just mean an actually bad injury so I continued back to the condo and called it a day. It’s already feeling better two days later. I’m really happy I was able to go up the mountain and board for real on my own. It’s a real sense of accomplishment.

Saturday we got up early in anticipation of an ugly drive back to Denver because of all of the snow. However, the roads were plowed and the traffic was light and we made great time. That meant that we were back in Denver with several hours to kill. We stopped for good coffee and lunch at Crema and then managed to catch the first tour of the day at the Breckenridge Brewery. They have quite the operation there and all of the people were really nice. Then off to the airport and back home. Arriving in Austin was funny because Bergstrom was packed full of visitors for SXSW which started this week. The line for Taxis was comically bad but we were parked so we didn’t have to deal with it.

Today I got up late, had Girl Scout Cookies and hamburger and have spent the rest of the day being useless. Back to work tomorrow, and for a good long while too since I’ve used all but three days of vacation for the year already.

Beaver Creek

I’ve gone to Beaver Creek with friends again. The last time was five years ago and while I was here then I was working on the application for the job that I have now. Snowboarding is still difficult for me but a day of lessons got me most of the way back to where I was before. Yesterday I went down the beginner greens at the base of the mountain in the morning and a little in the afternoon until it became clear that I was falling too much because I was tired and couldn’t control my board well enough.

I’ve been doing some cooking. I made waffles Sunday morning and Green Chile Mac and Cheese Sunday night. Last night we did spaghetti and roasted acorn squash. Today is a rest day for me so I’m probably going to do some grocery shopping and take a walk and see if I can find a place or two to do some photography. Last night and then early this morning I took some long exposures from the balcony of the fabulous condo. I have my first pictures with visible Milky Way now which is pretty exciting.

Bottling Day

Bill and I bottled our beer Sunday afternoon. It’s been a long voyage to beer and I suppose it isn’t quite finished yet since we have to let the bottles condition for a couple of weeks before drinking them.

We ended up getting 40 and one half bottles which is less than we’d hoped by 20% but at the same time we’re pretty sure we didn’t contaminate anything and it looks really good so I think it’s ok for a first try. I took mine share home last night and stuck it in the guest bathtub in case any of them decide to lose structural integrity.

Then I did some laundry and went to bed early.

Today I’m back at work. I’ve cleaned up my email so I guess I’m ready to be productive again.

Last Days

It turns out the aurora came back for a second encore. Apparently after we left the Arctic circle the solar wind strengthened again and there was a good two days of impressive lights but we were too far south to get a good view. We could see it but it was low on the horizon and smallish. However I did get a bunch of short, high ISO exposures and I was able to string them into an animated gif.

aurora

We arrived in Bergen in the early afternoon, got on a bus and then on a sequence of airplanes and got back to London. This time we decided to leave Mom’s big suitcase at the airport bag storage since we were only going to be there one day. The next morning Mom got up and went to St. Paul’s and I slept in. Then we went to the Natural History Museum and then to Piccadilly Circus for touristy shopping and gawking.

The next morning was back out to Heathrow and then onto another series of planes including a two hour delay at O’Hare with a gate change, a plane swap, calling in a standby flight attendant and getting airborne only a couple of hours ahead of an incoming snow storm. Lesson learned: Chicago is the airport of last resort and you should not try to connect through it unless you have no other options.

I finally got back home yesterday afternoon and today Bill and I are going to attempt to bottle our beer after five weeks in secondary fermentation (three weeks longer than expected).

Encore

I had assumed that, being so far south as we were last night, we would be done with aurora. We had a howling gale for most of the evening and pretty stout waves that were making the boat roll quite a bit. I’d had enough of the uncomfortable wobbling and was going off to bed when one of our tour members walked past saying there were lights in the northern sky. I went up on deck with none of my usual cold weather gear and there it was, low on the horizon. I ran downstairs, suited up, waking Mom in the process and went back out. There was visible green. There was movement. There was also miserable ship movement and salt water spray. I was debating getting my camera and our tour leader John was there and he was having the same debate with himself and then he said “The hell with it” and ran to get his so I followed suit. This time I tried ISO 4000 and 3″ so I could get quick pictures to try to combat the motion of the ship. I think I got enough pictures to maybe string together a little animated gif when I get back home. I also failed to use the intervalometer correctly and ended up with a 24 second exposure that is not very good but has a neat effect. At the same time, the ship was passing a fire on the port side that was apparently 25 acres of burning heather and dried grass. That produces a somewhat different kind of night sky illumination.

So I ended up in bed late again and then this morning Mom and I got up early and went for a walk in Trondheim. We had hoped to browse in a few shops and maybe get a few things but the only things open at 7-8:00am were convenience stores and coffee shops. Too bad. It was still fun to walk around and see things from a more typical tourist’s perspective rather than as part of a group. Today was mostly reading in the early afternoon and then a nap before dinner for me.

Tonight is the great repacking of the suitcases. We have to have those out for the crew before 10:00AM and we likewise have to vacate our room by about then. We have lunch on board and then come into Bergen at around 14:30. From there we take the bus to the airport, a plane to Oslo, a different plane to London and then finally most likely the Tube to Gloucester Station and our hotel for two nights. We have a day in London for sight seeing and then Friday noon our flight leaves for home. I’ve been a little melancholy (perhaps too dramatically so) today. I’ve had a great trip up the coast and back. Norway is incredibly beautiful and the aurora is something that will stay with me for the rest of my life.

Stories from Norway

January 22nd:
Tonight was amazing. Bright aurora that you could see color in everywhere for several hours.

Is what I put on Facebook. We’ve been fairly busy and I’ve had other things to worry about so I’ve been bad about the blogging. That night we went out on deck after leaving Tromsø and there was a wonderful display. The lights stretched across most of the sky and one band was running North to South which is unusual. It was bright enough that you could see the green without the camera although it is not as bright and saturated as the camera sees. In another band you could see the rays shimmering and moving and it’s easy to see how people might have thought it was the souls of the dead walking to their afterlife. Unfortunately, it was cloudy below where the main display was so we mostly got a diffuse green glow there and the camera has clouds silhouetting the light and being lit from behind. After a while, I couldn’t say how long, I got cold enough that I came inside and copied my pictures onto the computer and as I was going through them I had a group of Germans come and watch over my shoulder and then later an English couple who asked me to send them one of the pictures. Then I looked up, out the observation deck window and saw a big green loop and threw my gloves and hat back on and ran back outside for part two.

The second bright display was equally dramatic and had more distinct features and movement, though none of it was overhead. It did have a large fan of lines which curved toward the ship which made a nice perspective view. After a while the display dwindled and the clouds moved in more and that was it for the evening. I’ve uploaded all of my pictures of the evening to http://thwartedagain.com/zenphoto/norway/Norway/ as per usual and I’m pretty happy with them. The camera settings I was using to get the bulk of them were 7″, f/2.8, ISO 2000. It was bright enough that I could drop the ISO a bit and the sea was calm enough to allow a longer exposure to make up for it. The stars still mostly have little movement trails but it’s not too bad and there is good detail and color in the aurora.

We have been very fortunate to see a display as good as this with the Earth and Solar weather being what they’ve been.

January 24th:
We had a snow day today too.

While our friends and family back in Texas are having Snowpocalypse 2014, that being some freezing and a frosting of snow and ice, we spend the afternoon visiting Kirkenes (pron. Tchirknes) and the Snowhotel. The rooms of the Snowhotel are rebuilt every year. They melt enough to become uninhabitable in early spring and are gone shortly after. They make them by inflating “balloons” which are like bounce houses that are the room and hall shapes and then covering them with snow. After a few days the snow is packed and stable enough to deflate the forms. After that a team of Chinese artists come and make carvings in the walls, a different one for each room, and then the ice sculptures are moved in. There are also some non-snow Swiss cabins that are brought to the location for those who require a warmer night’s sleep. The beds and seats have closed cell foam and blankets and you sleep in a big down sleeping bag. The dining tables in the common room are giant slabs of carved ice and apparently the bar serves drinks in ice glasses although it wasn’t open when we were there.

There were high but heavy looking clouds the whole time and the sky was almost the same color as the snow covered landscape. It was pretty but kind of desolate.

Kirkenes is the turning point of the voyage and from there we started sailing back to Bergen.

January 25th/26th:
We visited a lot of little ports on the 25th very briefly and then stopped in Tromsø at 11:45. Mom and I had signed up for the Arctic Cathedral midnight choral performance so we got off the ship, onto a tour bus and they drove us over the bridge to the cathedral. A lot of the churches and other buildings in Norway were rebuilt after the second world war because as the Russians drove back the German occupying forces the cities were burned to the ground to slow the advance. In a few places some buildings survived but a great many things are new and, as a result, have a modern feel to them. The Arctic Cathedral is very modern looking and is also very beautiful. It is essentially a series of nested triangular prisms with the doors and pipe organ on one end and an entire wall of stained glass on the end behind the altar. We have visited several churches that share this general design but it seems like this is this best example.

I was expecting something like a typical church choir, a few people in each of the usual vocal roles and maybe some organ music to accompany them. What we got instead was one man who played the organ and later a piano, a cellist and a single soprano. It was excellent. The church has a great sound and the singer was superb. She could make herself barely heard or fill the entire space and every sound was perfect. The instrumental accompaniment was equally good. I would have paid good money for a recording, knowing full well that my home stereo could not reproduce the magicial sound but strangely there was no recording on offer. It’s a shame really. We did get program with the performers names so hopefully I’ll be able to find out more about them and maybe even find something they have recorded.

Sadly aurora watching has been mostly a bust. There was a little green splotch hidden by bunch of clouds the night before. That night there was little to see as well. The clouds have been chasing us from Kirkenes.

————————————————————————

January 26th:

This evening we stopped in Svolvær and rather than eating dinner on the boat my mother dragged me out into town and made me try to order a pizza in Norsk. Our blonde pixie waitress greeted us and probably said something about what would we like or “your hat looks stupid” or something and I stammered “Jeg forstår bare lit Norsk” and was starting on “Snakker du Engelsk?” when she asked if I’d rather speak English.

So we got a pizza with pepperoni, pineapple (most of the pizzas had pineapple a.k.a. “ananas”), red bell pepper and some kind of ground meat. I got a Coca-Cola and mom got et glass øl.

So now we’ve indulged our Americanness and tomorrow it’s back to fish and reindeer stew and bowls full of berries covered in whipped cream. That last being not anything particularly Norwegian but rather what constitutes about half of lunch for mom.

Our stop tonight was in Svolvær again. We had previously gone on a walk with Inger and she had pointed out that most restaurants are closed on Sundays or have limited fare which had caused her trouble with a tour group in years past there. However, she continued, “Viva Italia” had a broad menu including Kebab, Pizza, Salads and other things. Mom had decided that instead of eating dinner on the ship we should go into town and find a restaurant to eat in, seemingly having forgotten the part about nothing being open. But we talked to Inger and remembered her story so we walked to Viva Italia. I was, of course, dreading having to try to order dinner for the two of us in a language in which I have a roughly 60 word vocabulary and have never tried on another human being, only responding when prompted by the audiobook playing on the car stereo while commuting to work in the mornings.

We walked into the restaurant and a tiny blonde woman, probably only 25 years old, if that, greeted us and took us to a table and then said a bunch of Norwegian things that I didn’t understand at all. I mustered all of my 16 lessons of Pimsleur Norwegian and informed her in broken, almost unintelligible Norwegian that I understood very little Norwegian and I was working on asking her if she spoke English but she got there ahead of me. So we ordered in English and she asked where we were from and we told her. She, it turns out, is not Norwegian either but rather Polish which means that she actually speaks at least three languages and I imagine probably more. Meeting people like that makes me feel completely useless but I suppose there’s nothing to be done aside from maybe try to learn more language.

Oddly enough, most of the pizzas had “ananas” a.k.a. pineapple. We got a large with pepperoni, pineapple, red bell pepper and some kind of ground meat. It was actually pretty good. They cut the pizza into squares rather than pie slices which was a little odd. Mom had the ubiquitous “Arctic” lager and I had a Coca-Cola. A little taste of home in the dark and cold.

Up on deck that evening we saw a few faint auroral arcs and one bright blob just on the horizon and then that was it. The sky was perfectly clear but there was a strong wind blowing from the west which meant rough seas and the ship was rolling and rocking which doesn’t do wonders for me and makes it basically impossible to take decent pictures. I watched the sky off and on until a little after midnight and then gave up and went to bed. That’s probably the end of the aurora for me for a good long while. It has been beautiful and awe-inspiring and I will miss it greatly. I could see coming back here for lights again or even in the summar since Norway, for all of its expense is welcoming and I’ve had fun. But I also would like to go to Iceland or Canada or Alaska and see the lights again there too. Canada would be exceptionally cold but supposedly north-eastern Iceland is a great place to see the lights and it stays reasonably warm even in the middle of winter because of its position in the gulf stream. Plus there’s lots of natural beauty there as well.

Nordlys

Tonight, on the way between Stamsund and Svolvær we went out on the back deck / helipad / night observatory and saw the Nordlys. Unfortunately they were not bright enough to appear green to the unaided eye but they were there and we saw them. The camera is much better at seeing color at night, particularly when you use a longer exposure time.

Last night I was able to get a few pictures of a “quiescent homogeneous arc” with both green and a little red but it was so faint I couldn’t see it with my eyes, just the camera. Tonight was much better on the first outing as I said above. After the stop in Svolvær we went back out and there were some lights again but they were less visible. We also the ship into the Trollsfjord; that being a narrow fjord with an entertaining history about a battle fought between fishing boats over access rights. It is narrow enough that the ship only just fits into it and because it is dark and windy they just positioned us at the opening and used the spotlights to let us see into it. We also walked through a couple of the little towns we’ve visited which was nice. We tried to find the state liquor monopoly store in Bodø but were unable and that’s probably just as well because the tax on alcoholic beverages is 80%.

Today was also the day we crossed into the Arctic Circle. We went up on the top deck at 7:00AM to watch the ship pass the marker and have a glass of breakfast champagne. Then we ate breakfast and I went back to sleep for another four hours, completely missing the visit from Neptunus Rex. Despite my inexcusable absence, mom and I still received certificates proclaiming our legendary adventuring prowess for having crossed into the Arctic. They’re signed by the Captain and everything.

All-in-all, a pretty exciting day.
