Yeast!

Over the last few weeks I’ve been caring for a few billion microorganisms. And ate some of them.

Making a wild yeast starter turned out to be pretty easy. It took about ten days (in contrast to the five specified in the recipe I followed) for the colony to reach maturity in this winter kitchen, fed twice each day with equal parts flour and water, left at room temp overnight. Now, they are on a weekly maintenance schedule.

So far, I’ve used the starter in a hybrid (part commercial yeast) sourdough boule, two fully wild yeast loaves, pancakes, and, of course, pizza.

Compared to straight pizza dough, the sourdough version has a more complex taste, with basically the same texture. There is not much difference in the way the dough handles.

The wild yeast breads were both a little flatter than I’d have liked, owing to the less predictable rise; on the other hand they had a very nice sour taste. The hybrid dough is a nice compromise: less sour but airy crumb.

Pancakes of any stripe are always awesome.

State of the pizza

It has been a year since my last statement about home-made pizzas, so it may be a time to serve up (deliver?) an update. Here’s one from the most recent batch:

Ken Forkish’s straight-dough, low yeast, long-rise recipe continues to be my go-to, and there is little left to complain about. It has a great crumb and nicely developed taste, especially when the dough is a day or two old. I still do need some work on the technique side: getting an unbaked pizza off the peel — without using so much flour or cornmeal as to mar the taste — still eludes me. Thus, I have settled on using parchment paper for the first couple of minutes, then, after the crust firms up, lifting the pizza with tongs and yanking out the parchment paper before it incinerates in the 550 degree oven. This, it should be said, is a maneuver not without danger to one’s fingers.

Our grocery carries “pizza yeast” in addition to the normal stuff, so I decided to give this a try to see how it stacks up. Apparently, the packet consists of highly active yeast along with some conditioners that make a thirty minute dough handle like one with a longer rise. The resulting dough was as easily stretchable as advertised, but also had little to no strength. It was altogether too easy to tear a hole while trying to shape it into a round, but I persevered. Here is the side-by-side (pizza yeast on the right):

The resulting crust was rubbery and tasteless, so my advice is to not bother repeating this experiment.

I am considering branching out into a wild-yeast version next, depending on whether I can manage to get a viable starter going.

Carbs

My brother-in-law gave me a copy of the bread cookbook Flour Water Salt Yeast by Ken Forkish (as far as I know, his actual name) for Christmas, and so I made five pizzas. The one pictured below is a touch over-baked on top, but pretty close. It was a little too chewy owing to having used bread flour, yet had a nice airy crumb. I think this replaces Peter Reinhart’s recipe as my go-to from now on — both are about 70% hydration but this one had more bubbles.

The book has some tips for baking it in a home oven, which were pretty useful, though I found his suggestion of temporarily using the broiler caused my oven temp to drop 30 degrees in the process. Still working on the heat aspect, but I’m getting better at dealing with wet doughs.

Incidentally, this one is for the kids: my own favorite toppings, stolen from a pizza joint in Crystal City, VA, are prosciutto and arugula.

Homemade pizza

Also cooked last week: pot roast with homemade egg noodles, and butter chicken.

Homemade noodles

Whew, I think it’s going to be takeout all this week.

Fake Tassimo Cleaning Disk

My particular first world problem: it’s too easy to lose the cleaning disk that came with my coffee machine.

The item in question is just a plastic disk with a certain barcode. As I and many others have found, it is easy to print out a new barcode, tape the barcode to a used milk disk, and you are back up and running. Here is my contribution: said barcode in a PDF file ready for printing on Avery 5167 return address label sheets. Then, when you inevitably accidentally throw away your stand-in disk (which we have done a half dozen times so far), just peel off another label after your next latte.

If you have different label sheets, I recommend glabels3 to set up the template. The barcode value is “07879” using 2-of-5 interleaving (GNU barcode backend can generate these).

Update (03/2024):

Long ago this Tassimo bit the dust and it got replaced, bringing with it a new disk with a different barcode. Since this page still gets a lot of search traffic, here is an image of what that cleaning disk looks like in case any intrepid visitors need to reproduce it:

Cooking with gnuplot

Over the winter holidays I was put in charge of cooking one (of several) of the family dinners. At my house, a Christmas dinner can mean only one thing: prime rib is on the menu. The local grocery store had a great deal on rib roasts, so I bought a whole one. All seven ribs, 25 pounds of it. When it came time to cook this beast, I did plenty of reading, and settled on this seriouseats recipe. I guessed at about six hours to slow-roast the behemoth. But after a few hours of roasting, I decided it would be nice to know whether it would finish in time for the guests, or whether we would have to invent some pre-meal activities to stall.

Linear regression to the rescue! I had a leave-in meat thermometer plugged into the slab of cow, the type with a cable that runs outside the oven so that you can read the temperature without opening the oven door. It was then a simple matter to record the temperature every fifteen minutes and plot it to see how it was going. My uninformed guess was that the temperature curve is really sigmoid-shaped, but linearity is probably close enough around the target range.

Gnuplot can do linear regression for you:

f(x) = a*x + b
fit f(x) 'temp.dat' u 1:2 via a, b
set xrange [-5:160]
plot 'temp.dat' u 1:2 w linespoints, f(x)

This produces a graph like the image below, which shows that after 3 hours of cooking, the meat would be around 128 degrees (I started keeping track about three hours in).

In the end, I turned up the oven a bit in the last hour to speed things along. The meat turned out great, although I didn’t have too much luck with the in-between rest that the recipe promotes: there were still plenty of juices all over the place at carving time. Next time, I believe I’ll just turn the oven up to 500 deg. F when the interior target temperature is reached, and then do a normal rest afterwards. Another lesson learned: a full rib roast is perhaps twice as much as needed for eight people, but I am not one to complain about having prime rib leftovers for a week.

Blowtorch Cuisine

Ever mindful of fire safety, I’ve had a full propane canister (the small blowtorch size) rattling around in the back of my trunk for two and a half years. Luckily our car never decided to explode, but just in case, I’ve decided to finally use up the fuel.

Since I plan to never do any sort of plumbing again, the natural application for my blowtorch flame is on food, specifically crème brûlée. So I baked up some custard in my soup bowls, tossed some sugar on top, and burnt that bad boy.

The problem is these torches really only work well upright, so you wind up having to bring the food to the flame rather than the other way around. I did at least have my fire extinguisher at the ready in case a wall decided to ignite. The smoke detector only went off once.

Our tasters were split on the outcome. Ange really liked it. I thought the custard was a bit too eggy, but that could be the recipe or personal taste. As I’m not a big CB eater, I don’t really have much to compare it to. It looked good, though.

Next up, fire grilled cheese?

Pork

Inspired by the ‘tinga’ (Mexican roast pork tostadas) recipe in this month’s Cook’s Illustrated, I bought a $12 picnic shoulder at the grocery store on our last trip out. The recipe recommends a boneless boston butt instead, which is probably a good idea given all of the tendons in the lower cut. But my grocer only had the shoulder and it’s cheap so what the heck.

I spent last Saturday morning carving all of the meat off of the bone, at which point I realized just how much pig we’re going to be eating for the next few weeks. As Ange and I try to subscribe to the ‘use everything but the squeal’ philosophy, I portioned the slab for various future meals: two pounds of meat for the aforementioned tinga, a couple of pounds cut into thin slabs for char siu, about another pound or so of trimmings for barbecue or pork tacos, and the bones went into the freezer for congee.

Which left a big hunk of skin. I tried making cracklings out of this, but the porcine gods were not having it: it was a big sticky mess. I ultimately gave up after a one sizzling piece of skin and lard hopped out of the pan only to land on my face about a centimeter away from my right eye. Even fried pig skin isn’t worth blindness.

The tostadas were pretty awesome though.

Hummus

HummusAnge and I have been on a real Hummus kick lately for some reason. A container of Sabra is usually gone within a few minutes of being opened around here. So I decided to save a few trips to the store and try making it at home. Turns out, this is really easy: dump a can of chick peas, 1/4 c each of olive oil, water, and tahini (finding this is the hard part), a garlic clove and 1-2 tbsp of vinegar into the food processor, and press “On.” A little time spent chilling in the fridge and it’s good to go. A couple of roasted habaneros wouldn’t be a bad addition, either.

I also made my own pita chips from pita bread. While tasty and a lot cheaper than pre-made chips, I think that is far too much work when you’re hungry.

Sausage fest

5000 Calories of AwesomeWhenever I have some occasion at which I am to provide a side item or hors d’Å“uvres, I consider making the quintessential party treat: sausage balls. I think these are a Southern US mainstay, as no one around here seems to have encountered them before, whereas in my youth they made an all-too-brief appearance at many a gathering. Take it from me and my waistline, these things are full of win.

The classic recipe goes like this:

2 c Bisquick brand baking mix
10 oz medium chedder cheese, grated*
1 lb breakfast sausage**

* Sharp tends to be too dry. I also freshly grate it with the food processor since block cheese usually has more moisture than packaged grated cheese.
** Jimmy Dean “Hot”. Spicier is better.

Preheat oven to 350°. Mix everything together with your hands until it forms one big lump. Roll into 1.5-2″ diameter balls. Place on a cookie sheet and bake for 20 minutes or until golden brown. Cool before serving.

It doesn’t get much easier than that. However, I’m not crazy about relying on Bisquick; if we ever buy it, it stays in our fridge forever. I make biscuits frequently, but I find Bisquick biscuits to have a very chemical, baking soda taste that reminds me of pancakes. Maybe because I’m too lazy to make pancakes from scratch, so if I ever do, I use Bisquick — guess how often we have pancakes.

Anyway, I always have the components for home-made biscuits on hand, so I thought I would make an extra batch without Bisquick and see how it went. I took my normal biscuit recipe (stolen from Alton Brown), replaced the butter with shortening, as I thought the butter would make it too greasy, and supplanted the Bisquick:

2 c flour
4 tsp baking powder
3/4 tsp salt
1/4 tsp baking soda
4 tbsp buttermilk mix (my one cheat with biscuits, but it works great)
4 tbsp vegetable shortening
1.5 tbsp water
[rest same as above]

As indicated, I added a little water, because I found the Bisquick mixture to be a bit more moist than the flour mixture (I guess it has a little more fat in it). If the mixture is too dry, the ingredients will crumble rather than form a cohesive whole.

The result? The cheese and sausage really overwhelm the flavor of the dough, so there’s not much difference in taste. In texture, the Bisquick balls are chewier, while the from-scratch version is a bit lighter. It’s rather subtle, so while I somewhat prefer the latter, it’s not generally worth the extra effort. But since it saves me from buying biscuit mix, it’s a winner in my book.

Next time, I’ll try using chorizo.

Berlin eats

Ange and I are back in the States after our wonderful break abroad. Now we’re home again, delighting in such missed American excesses as air conditioning, queen-sized beds, and monolingualism. The latter, actually, is our biggest regret of the trip: the next time we visit a country we’ll have to plan ahead and take a few language courses. Even so, we picked up the basics during our immersion, achieving a fluency on par with, say, a one-year-old who takes the subway a lot.

Our first exposure to Berlin cuisine was at a coffee house where we had a few of the sweet pastries that give the city its name, if I interpret that old JFK myth correctly. Jelly doughnuts, doughnuts shaped like pretzels, strudels, cheesecakes, cheese pastries, and so on were also amply supplied gratis at our hotel, so snarfing down on cakes with tea on the patio quickly became an afternoon tradition during the trip.

For street food, the main contenders seem to be all sorts of sausages, especially the currywurst preparation, and the döner kebab. Currywurst is essentially a sausage sprinkled with curry powder and doused in ketchup. It’s very good — any sausage in Berlin is about 50 times better than the brats one can get at home, though neither of us were really sold on the necessity of the curry powder. Not bad, just different. The döner kebab is more or less a gyro served in a spongy, focaccia-like pita, slammed with enough meat and vegetables to make holding it nearly impossible. I miss them already.

Our best dinner in a standard restaurant was at Florian, a German/Austrian restaurant around the corner from our hotel. The selection was game-influenced: Angeline had duck and I had a roast pig, all served with a hearty gravy and various starches. Both dishes were excellent; you can’t go wrong with roasted animals.

However, the culinary highlight of our trip was with the so-called “Shy Chef,” an underground restaurant. Our friends turned us onto this by sending us a story by Gisela Williams in a little-known rag, The New York Times. We were fortunate enough to grab a reservation the week after the story ran.

The evening before dinner, we got the email leading us to the restaurant’s secret location. Upon arriving, we found our way into a small Berlin flat with a table set for four. The proprietors are obvious bibliophiles, as is instantly inferred from the books spilling out of wall-length, floor-to-ceiling bookcases, and underscored by the Papa-inspired absinthe cocktails handed to us as soon as we entered the room. (As an aside, if number of bookstores is any indication, Germans are enthusiastic readers. We passed three independent bookstores every morning during the 50 meter walk to our nearby café. A far cry from our highly polished, soul-starved Borders and B&Ns.)

The hidden supper club is a wonderful concept: it’s very much like a dinner party with friends, only you don’t know your friends until you get there. The fare is as good as in any restaurant, but the authenticity and intimacy are unmatched. Our fellow diners hailed from NYC and Oxford and made for excellent company, as did our hosts.

I won’t go into too much detail of the menu, lest it lose some of the mystique, but the highlights for me were a velvety garlic-cauliflower purée with an inventive parmagiano reggiano “gratin”; thin-sliced salmon in olive oil with German bleu cheese, apple and cucumber matchsticks; and a very nice salty, paper-thin ham that recalled to me the country ham my Tennessean relatives cured themselves. The dishes were accompanied by generous wine pairings, together more wine than Angeline and I have had in the previous year or so, but all of them excellent choices. As the gentleman from Oxford said, the entire experience was “just brilliant,” and I am sure we’ll remember this dinner for quite some time.
