Everyday Fasting Sourdough Boule

This is the daily bread of the Orthodox faster. Four ingredients: flour, water, salt, and a sourdough starter. No oil, no dairy, no eggs, no commercial yeast. Xerophagy-compatible. Ready in a day and a half from a fed starter. Keeps for five days, freezes for two months. Works for toast, for tearing into soup, for hummus, for olive oil on a Sunday.

You need a mature starter. If you do not have one, see our sourdough article for how to build one from scratch in 7 days. Once you have a starter going, this bread becomes the easiest and most reliable thing you bake.

The technique here is the "no-knead" approach with a Dutch oven for steam. Every serious home sourdough baker eventually uses some version of this.

NUTRITION (per thick slice, 1/12 of a boule)

- Protein: ~5g
- Calories: ~150
- Fat: ~0.5g
- Iron, selenium, B vitamins from the whole grain
- Easier to digest than commercial yeast breads — fermentation breaks down phytates and some gluten
- Lower glycemic response than non-fermented bread

INGREDIENTS (makes one round loaf)

- 100g active, bubbly sourdough starter (fed 4-6 hours before)
- 375g room-temperature water
- 500g bread flour (or 400g bread flour + 100g whole wheat for more flavor)
- 10g fine salt (about 2 tsp)

EQUIPMENT

- Large bowl
- Kitchen scale (strongly recommended — volume measurements are unreliable for sourdough)
- Dutch oven with lid (essential for the crust)
- Parchment paper
- Optional: proofing basket (banneton) or a bowl lined with a floured towel
- Bench scraper and a lame (razor) or sharp knife

METHOD (TIMING: 12-24 HOURS TOTAL, MOSTLY HANDS-OFF)

1. Mix (9:00 AM): Combine starter and water in a large bowl. Mix until the starter is dissolved. Add flour and salt. Mix with your hand or a spoon until no dry flour remains. It will be shaggy. Cover and rest 30 minutes.

2. Stretch and fold (9:30 AM - 12:00 PM): Every 30 minutes for the next 2-3 hours, do a stretch-and-fold. Wet your hand, grab the edge of the dough, stretch it up and fold it over the center. Rotate the bowl 90 degrees and repeat. Four folds per round, four rounds total.

3. Bulk ferment (12:00 - 5:00 PM): Cover and leave at room temperature until the dough has risen 50-75% and looks jiggly and bubbly on top. Time varies from 3 to 8 hours depending on room temperature and starter strength. In a 22°C kitchen, expect 5-6 hours.

4. Shape (5:00 PM): Turn the dough out onto a lightly floured surface. Shape into a tight ball by pulling the edges to the center and flipping seam-side down. Let rest 5 minutes, then reshape tighter. Transfer seam-side up to a floured proofing basket or a towel-lined bowl.

5. Cold proof (5:00 PM - next morning): Cover and refrigerate overnight (10-16 hours). This is the magic step — the slow cold fermentation develops flavor and makes the dough easy to score.

6. Bake (next morning): Preheat oven with the empty Dutch oven inside to 260°C (500°F) for 45 minutes. This preheat matters. Do not shortcut it.

7. Turn the cold dough out onto a piece of parchment. Score decisively — one deep slash across the top with a razor or sharp knife, angled slightly.

8. Using the parchment as a sling, lower the dough into the hot Dutch oven. Cover with the lid.

9. Bake covered at 245°C (475°F) for 20 minutes. Then remove the lid and bake uncovered for another 20-25 minutes until deeply brown — darker than you think. The internal temperature should be 95-98°C (200-208°F).

10. Cool on a rack for at least 1 hour before cutting. Cutting hot sourdough gums up the crumb. This is the single rule of sourdough: do not cut it hot.

STRICT DAYS AND XEROPHAGY

This bread is oil-free, sugar-free, and contains only flour, water, starter, and salt. It is permitted on every fasting day, including xerophagy. A slice of this with olives and raw tomato is a complete xerophagy meal with centuries of Orthodox precedent.

NOTES

The loaf keeps cut-side-down on the counter for 3 days. After that, wrap in a bag and it is good for bread pudding, croutons, panzanella, or toast for 4 more days. Freeze half the loaf right after cooling if you will not eat it in 3 days — sliced first, so you can toast from frozen.
