A lazy Saturday calls for...

... a Master Cleanse. While this will not end up being a lazy Saturday (I've been working my butt off all week, and will be in the lab all day today), still, an evening cocktail provides a chance to slow down, if only for a few minutes. This cocktail comes from the newest cookbook in my collection, The Art of Living According to Joe Beef. The cocktails in this book look magnificent (three of them feature meat products), but having just visited a sugar shack, I had to make the maple syrup cocktail, the Master Cleanse. I used a dark maple syrup from Thurston & Peters, natch.

Cocktail
½ cup maple syrup
½ cup fresh lemon juice
pinch of cayenne pepper
1 oz bourbon
sparkling water
While Joe Beef calls for heating the maple syrup and lemon juice, I did not. I merely mixed them well until the syrup no longer made ribbons in the lemon juice. Add the cayenne and bourbon. Mix well, and pour over ice. Top with sparkling water and serve. Joe Beef calls this one cocktail. In the Dude household, this made two very generous cocktails. This is one of the best bourbon sours I have ever had, and the ½ cup of maple doesn't come across as overly strong (indeed, you only get a hint of maple). But I might dial up the bourbon a tad next time.

I expect this cocktail to become a staple in our home. Going to have to sign up for bulk purchases of maple syrup.

Sauerkraut

I'm a microbiologist. But I had made neither cheese nor sauerkraut in my home (until recently). No home microbiology (save wine and mead fermentations) have occurred in my home. During the day, I'm working my butt off to develop a rapid, sensitive, diagnostic test for Listeria contamination in food. Listeria is a deadly pathogen that can contaminate all kinds of food, but is most commonly associated with contaminated, unpasteurized dairy products. Given that I study food-poisoning, I'm rather more cautious in that area than most families.

It turns out, sauerkraut production is pretty toxic to to many food pathogens. Sauerkraut production is basically making an environment that makes Lactobacillus bacteria happy. If the salt concentration is high, and the environment is anaerobic, Lactobacillus will happily grow and piss out large amounts of lactic acid. Lactic acid is particularly toxic to non-lactic acid bacteria, translocating into the cell and dropping the pH of the cell in a way that many other acids don't. It's an excellent preservative. And it makes cabbage taste delicious. So win, win!

I used a sauerkraut recipe developed from a couple of online sources, and a brine developed from Charcuterie.

You'll need one piece of specialized equipment. An inert container (i.e., not plastic or metal). Either a glass (not a good idea, you might break it) or stoneware crock, and an inert item to cover it. I used a tight-fitting stoneware plate.

Cabbage
~ 2 lb cabbage (1 cabbage)
10 juniper berries
1 tsp caraway seeds
1 tsp yellow mustard seeds
1 tbsp sea salt
Chop the cabbage finely.

Shredded cabbage

Mix with the salt, and pack it into the crockpot tightly.

Shredded cabbage

Sprinkle the herbs on top. Place your tight-fitting lid on top, and put something heavy on it. I used a 1 liter water bottle, and pushed down on it to squish the cabbage. This is important. The salt will draw out the water in the cabbage (pretty quickly, as it turns out - 4 hours after I mixed the cabbage and salt, water had filled up to the top). On top of the water bottle, I placed a tea towel, to keep out bugs and dust.

Every day, push down on the cabbage to squeeze out any air. Should it look like the water level is receding, top up with brine to keep all the cabbage submerged (to keep it anaerobic). Brine consists of:
1 cup water
1 tsp salt
Now you wait. Keep the sauerkraut cool, but not cold. The temperature in our house has ranged from 12°C to 20°C. At the end of the first day, there was a lot of water. By the end of day 5, that water was fizzing (that's carbon dioxide being produced as part of the fermentation of the sugars in the cabbage - the other byproduct of that is lactic acid). And at a week, the brine turned cloudy.

Fermenting

The cloudiness is the lactic acid bacteria themselves, present in high numbers.

By the end of two weeks, the fizzing had slowed, the cabbage had softened, and the cabbage had a faint smell to it. I've scooped out about ¼ of it.

Sauerkraut

It has a more serious crunch to it than commercially sold sauerkraut, but the acid is definitely there. It's both subtler and more complex than a canned sauerkraut. And, in a big win, the first sauerkraut that Mrs. Dude actually enjoyed. She liked it!

I served it with bratwurst on a bun. The acid and crunch go particularly well with the fat and smoke from the bratwurst. Delicious!

Bratwurst

This is a big win. You should make it at home. It's easy and requires little effort. Just patience, and a 30 seconds of diligence each day.

EDIT: Mar 19, 2012. Week 3, the kraut is more acidic and brighter than before. It continues to improve!

Thurston & Peters Sugar House

Sugar shack

Growing up, my father would set a meal budget for us when we went to restaurants in the city. Our meal couldn't go over $5.00, which often meant that we would order water as a beverage, and no appetizer or dessert. My father was similarly frugal about other food items, and steak was rarely seen in our home. But there was one item that was never scrimped on. Maple syrup. Aunt Jemima and other cheap imitators were never seen in our home. We always had the real thing.

Maple syrup has a vastly superior and more complex flavor than other, simpler sugar syrups. Indeed, even as a child, I knew that the imposter syrups couldn't compete on flavor. And Aunt Jemima knew it, too. In the 1980s, she would advertise her syrups had superior pouring properties to mere maple syrup. (Superior pouring properties? Seriously?) As an impoverished graduate student, I lived on a very tight budget, but I always kept real maple syrup in my home, even at the deluxe price of $1 an ounce.

We recently had the opportunity to visit a maple farm in Maine, Thurston & Peters.

Traditionally, maple sap was gathered in pails hung on taps stuck into the tree.

Maple trees

But modern maple syrup facilities have a network of tubes running from each tree into central collection tubes.

Maple trees

The central tubes run into the sugar shack, where a pump is pulling gallons of sap into a small tank.

Maple sap

This sap is visibly indistinguishable from water, and while I was fortunate to be allowed to taste it, it is completely flavorless. When it fills this tank, it is pumped through a filter into a larger holding tank.

Filtering the sap

Making maple syrup out of maple sap essentially boils down (pun intended) to two processes - 1) Concentrating the sugar and other tasty molecules and 2) Caramelizing the sugar. In days of yore, this was entirely accomplished by boiling down the sap. But given that maple sap is between 0.7% and 2.8% sucrose (the same sugar as found in table sugar), and given that maple syrup is 60% sucrose, that's a lot of boiling to concentrate your sugar 30-60 fold.

These days, the first step of concentrating the sugar and other tasty molecules is accomplished by reverse osmosis. It's much cheaper, and less energy intensive. The sap is concentrated to about 30% sucrose in this manner, and then it is poured into the maple syrup cooker.

Maple cooker

The syrup is boiled until it reaches a concentration of approximately 60% sugar. At this point, it is filtered through diatomaceous earth to remove any cooked chunkies. It is graded primarily on the color that it reaches while boiling down.

Maple batches

And from here, it can either be processed into maple candies (yum!)

or bottled and sold as syrup. We left with a bottle of syrup, at a vastly reduced cost compared to buying it in the grocery store.

Do visit Harry Hartford at Thurston and Peters Sugar House if you have the opportunity. He is happy to chat with you at length, and he has some very interesting stories to tell, both about the process and history of maple syrup.

Back bacon (Canadian bacon)

Smoker

The first time I'd ever heard of "Canadian bacon" was after I had moved to the U.S. in 1997. I'm a Canadian. At home, we refer to it as "back bacon". Only recently I've learned that's because it comes from the back of the pig (as opposed to regular bacon, that comes from the belly of the pig). Canadians serve back bacon on pizza and with eggs for breakfast. Americans use it for Eggs Benedict (which will be making an appearance here soon, I hope).

So as we near the end of our first winter in Massachusetts, it makes some kind of sense to make food that is commonly associated with the land of Winter. I modified the recipe in Ruhlman's Charcuterie:
4 liters water
1 ½ cups kosher salt
1 cup sugar
1 ½ oz pink salt ← the curing salt containing sodium nitrite, not pink-colored salt
1 tbsp dried sage
1 bunch fresh thyme
6 garlic cloves, peeled and mashed
one 4-lb pork loin
Mix all the ingredients (save the pork loin), and bring to a boil. Stir until the salts are all dissolved, then remove from the heat. Cool to room temperature, then chill in the fridge.

Brine

When the brine is chilled, place the pork loin in it.

Pork loin

I warn you, brining pork looks gnarly. Really, not pretty.

Brining pork loin

Keep in the fridge for 48 to 72 hours. Then remove from the fridge, rinse the pork, and pat dry. Place back in the fridge for 12 hours to dry out a wee tad.

Brined pork loin

Fire up your smoker. I like mesquite for bacon, so that's what I used for back bacon.

Smoking pork loin

About two to three hours at 225°F, until the pork reaches an internal temperature of 150°F. Cool.

Back bacon

Slice thinly. I served it first on a nice bbq pizza (Hawaiian).

Hawaiian pizza

Salty and bright. Meaty, with a hint of smoke and thyme. This back bacon is awesome. It'll be figuring in a few other dishes over the next few posts. I wish I'd made this one ages ago.
