Step 0: Sourdough Starter

To get started, you need to make a starter. This takes about 3–5 days but once it’s active it, can be stored in the fridge for months.

Step 1: Leaven

As far as I can tell, a leaven is simply a starter that has had a big feed in the last 6–12 hours and is therefore ready to use. If you want to bake regularly, you might be better off maintaining a leaven (with 200 g daily feeds) rather than maintaining a starter (with 50 g feeds).

50 g SOURDOUGH STARTER
200 g WATER (~26°C)
200 g FLOUR

Scale it with BRDCLC

  • Mix water, leaven and flour and let sit for about 12 hours.

The night before you plan to mix the dough, discard all but 1 tablespoon of the mature starter. Feed the starter with 200 grams of warm (78°F) water and 200 grams of the 50/50 flour blend. Cover with a kitchen towel and let the starter rise overnight at a cool room temperature (65°F). This is your leaven.

Step 2: Forming a Dough

Makes two loaves. Scale it with BRDCLC.

700 g WATER (~26°C)
200 g LEAVEN
900 g WHITE FLOUR (ALL PURPOSE OR BREAD)
100 g WHOLE WHEAT FLOUR

The freshness of the flour has a big impact on the flavor of the bread—buy the best you can find.

  1. Mix water and leaven together in a large bowl.
  2. Add flours and mix completely.
  3. Let sit for 30min to let the flour absorb the water.
20 g SALT
50 g WATER (~26°C)
  1. Add salt and additional water.
  2. Squish dough with your fingers to thoroughly mix in the salt.

Step 3: Bulk Fermentation

  • Turn the dough every half hour for 3 or so hours. Leaving at least 30 minutes after the last turn.

To turn, wet your hand and slide it between the bowl and the dough, then lift and stretch a side of the dough and fold it over. Going around the bowl and repeating three or four times constitutes one “turn”. The little air pockets form the basis of the crumb which will fill with gas during the bulk fermentation.

At Tartine, we try to maintain the dough at a constant temperature between 78° and 82°F to accomplish the full bulk fermentation in 3 to 4 hours.

During the first 2 hours of the bulk fermentation, give the dough one turn every half hour. During the third hour, notice how the dough starts to get billowy, soft, and aerated with gas. At this later stage, you should turn the dough more gently to avoid pressing gas out of the dough.

So far I’ve mostly put the dough in the fridge over night after turning. But I’m experimenting with forming loaves sooner and retarding for longer in the proofing stage, rather than splitting it over bulk fermentation and proofing…

If you let the bulk fermentation go too long, the final rise will be sluggish as the food that fuels the fermentation has been exhausted.

Step 4: Shaping & Proofing

  1. Dump out dough onto a clean bench.
  2. Lightly dust with flour and use your bench scraper to flip the dough onto the floured side.
  3. Divide in half if making two loaves.
  4. Fold in half so the outside is now mostly floured.
  5. Gently form a ball.
  6. Bench rest covered for 30min.
  7. Heavily dust proofing baskets with rice flour (or white flour if you don’t have any).
  8. Dust, flip, stretch, fold and form.
  9. Dust top of dough ball with flour then place in proofing basket seam up.
  10. Cover with a tea towel and rise for 3–4 hours, or put it in the fridge for 10–24 hours.

Knowing When Dough Is Properly Proofed

The biggest mistake I’ve made is over-proofing. The dough becomes really difficult to get out of the proofing basket and you get very little oven spring. To test, poke the dough with your finger: if it’s under-proofed it should spring back reasonably quickly; if it’s perfectly proofed it should spring back slowly but not completely; when it’s over-proofed it won’t spring back much at all.

Step 5: Baking

  1. Heat dutch oven or combo cooker in oven to 260°c (500°f). Set the oven to ‘bake’ so the top element is not on.
  2. Turn dough into dutch oven, seam side down, and score with razor.
  3. Replace lid, put back in oven and reduce temperature to 230°c (450°f).
  4. Bake for 20min then remove lid.
  5. Bake for additional 20min or until very dark (almost burnt).

The dough needs moisture to help it rise. Commercial baking ovens inject steam; regular ovens don’t. The dutch oven avoids this by being tightly contained, as the moisture from the dough evaporates it creates a humid environment. If you don’t have a dutch oven you could try baking in your heaviest oven-safe pan covered with a pot.
