Keep a Rye Starter!

I took a pizza class at Josey Baker Bread in San Francisco this month and picked up a great tip from the instructor, JB pizza baker Caitlin (sorry did not get a last name!). She told us the bakery keeps a rye starter. This has two advantages: rye is more active so your starter will have a higher likelihood of success and you’ll always be ready to make a rye loaf. If you want a white or whole wheat dough all you have to do is add white or whole wheat flour and a spoonful of your rye starter.

I keep a small amount, like three tablespoons of starter on hand that I feed every day. When I want to make bread I do a build overnight and the next day I’ll have the quantity I need to bake a loaf or make pizza dough. This week I switched my starter over to rye using the small amount Caitlin gave us. I’m baking a loaf today and it’s rising like crazy.

As to the pizza we made in the class it was probably the best I’ve ever had. It’s a quirky pie: the secret is a dark, almost burnt crust brushed with garlic olive oil and sprinkled with Maldon salt. They keep the toppings simple as not to distract from the cracker-like sourdough crust. They have a pizza night at the bakery every Monday from 5 to 8 in case you don’t want to roll your own.

Don’t Worry About the Boule: Bake Bread in a Loaf Pan

In the frivolous, pre-pandemic before-times I slacked off on my bread baking. At the beginning of quar, I prepper-panicked, hastily re-started my starter and fired up the Mockmill 100 grain mill.

Baking with a sourdough starter puts you on a collision course with the unpredictability at the heart of the “natural” i.e. non-internet world. For me the unintended randomness of my loaves came down to the discovery that I was using too course a grind with the mill. Thereafter, my loaves improved.

Even after that simple fix, I still get can get distracted by chores and forget to shape the dough in a timely manner, thus leading to what looks more like a pancake than an Instagram worthy boule. But if you’re not making bread for the ‘gram, you don’t have to do a boule or batard unless that really floats your boat. There’s nothing wrong with baking in a loaf pan. Sometimes it’s kinda nice to have a square loaf for sandwiches anyways.

The pan I have is a Pullman pan made by USA Pan. It’s square and has a lid. The lid is especially handy in that you can do the first 20 minutes of the bake with the lid on, thus sealing in the moisture which helps with loaf spring. You don’t need the fancy Pullman type with the lid but if you’re going to buy a pan I’d suggest getting a Pullman. I use a bit of olive oil to keep the loaf from sticking. If you don’t have a Pullman pan, you can cover any loaf pan with a piece of aluminum foil for the first part of the bake.

You have my permission. Bake in a loaf pan.

Lastly, I’ve been fielding some emails about what kind of mill to get. The Mockmill 100 has served me well. I’ll do a full review sometime in our quarantine part II future. If you’re curious about my bread recipe, I use Josey Baker’s 100% whole wheat recipe (with a higher hydration) that can be found in his book.

Participate in the Science of Sourdough Project

If you missed the short sourdough lecture I linked to last week, you can watch it above. To summarize, researchers at North Carolina State’s Department of Applied Ecology are attempting to figure out the biodiversity of sourdough cultures from around the world. One of the questions they’d like to answer is how the type of flour you feed a starter influences its taste and viability. This is where you can help through their Science of Sourdough Project. Using the simple instructions on that site, you create a new starter with whatever flour you have on hand, record the results and send that data back to the researchers. If you’re a teacher or a parent this would be an easy science project for our days in quarantine. I’m going to participate and share the results on this blog.

Timing Sourdough Feeding

A recent “quarantine” loaf.

There are many paths up the holy mountain of sourdough bread baking. Wildly different methods will yield acceptable and edible results. But, no matter the method, I think one factor is important if you want to get a decent sourdough bread: the amount of time between feeding your starter and making your dough.

I keep a small amount of starter on hand since I bake, at most, twice a week under normal circumstances (Under quarantine I’m baking a lot more but the reasons for that would be the subject of another blog post). Just before I go to bed, the night before I’m going to make bread, I take a tablespoon of starer and add it to 50 grams of whole wheat flour and 60 grams of water. The next morning I have a little over 110 grams of starter with which to make my dough.

Starter float test.

Here’s the critical issue of timing: while I’m sleeping the sourdough culture is growing exponentially in the flour/water mixture. I need to make my dough within 8 to 12 hours of that feeding. If I wait too long the sourdough starter will lose its vigor. How do I know the starter is ready to use? I do a float test. If you gently spoon the culture into some water it should float, an indication that it’s active and full of CO2 bubbles. One of the most common mistakes with beginning sourdough bakers is not feeding the starter enough (you should feed at least once a day or put it in the refrigerator if you’re not going to use it) and trying to make a loaf with sourdough that’s been sitting too long after its last feeding.

To review my process:

  • The night before I make bread I mix one tablespoon of starter with 50 grams of whole wheat flour and 60 grams of water.
  • The next day I make up a dough and let it rise for approximate four hours at room temperature (this first rise is also called a bulk fermentation).
  • After the four hour bulk fermentation, I shape the dough, put it in the refrigerator and bake the next day. This second period of fermentation is called “proofing”). I’ve found that putting the dough in the refrigerator to proof has a few advantages: it develops a richer flavor, the dough is easier to handle, it’s less likely to stick to the bread form, and you have flexibility in terms of when to bake the next day.
  • When it’s time to bake I pull the dough out of the refrigerator and put it straight into a 475º F (246º C) oven.

So, in total, my bread baking process takes 2 days. You have to think ahead but there actually isn’t much work involved since I’m using a no-knead method. Again, it’s not the only way to make sourdough bread but I’ve found this method works well for me. For exact recipes and techniques I highly recommend the book Josey Baker Bread (library link). What I like about Josey’s book is that it’s kind of like a class in bread baking. He starts you out with simple loaves and then gets into more advanced techniques. There’s plenty of illustrations on top of the fact that Josey is a really nice dude (I’ve had the pleasure of meeting him).

If you’re interested in the details of my starter method I did a video about it.

Stay safe and happy baking! As Josey Baker says, “Make Awesome Bread – Share the Loaves!”

Make Pizza in Your Oven

In addition to sharing a name, Eric of Garden Fork and I seem to exist in some sort of synchronicity vortex. This past Saturday, after I finished teaching a bread class in which I used the same dough to demonstrate how you can make pizza in your oven with a cast iron skillet, I settled down on the couch to catch up with Eric’s YouTube channel. And guess what he was demonstrating?

I first learned about this technique from Josey Baker. Basically, you start the pizza out on the stove top and finish it under your oven’s broiler. I’ve found that it works almost as well as having an outdoor pizza oven and it’s a whole lot easier.
