A seven-day journey in flour, water & time
No commercial yeast. No shortcuts. Just a jar of flour and water, a week of feeding, and the oldest leavening method on earth. Follow the full journey — from the first bubble in the mother to the first crack of the crust.
Begin the journey
Equal parts flour and water. That's the entire recipe. Wild yeast and lactic acid bacteria live on every grain of wheat and in the air of your kitchen — the mother is simply a home you build for them.
Each day you discard half and feed her fresh flour and water. By day three she sighs her first bubbles. By day five she smells of green apples and yogurt. By day seven she doubles in six hours and you know: she's ready to raise bread.
Sourdough is not kneaded. It is coaxed. Mix flour, water, salt, and a few spoonfuls of the bubbling mother — then let time build the structure for you.
Every half hour, wet your hands, lift one side of the dough high, and fold it over itself. Four folds, four times. Between each set, the dough rests, ferments, and quietly transforms from a shaggy mass into something smooth, glossy, and alive — jiggling like a held breath.
The oven spring is the payoff for a week of patience. Cold dough meets a roaring Dutch oven, trapped steam keeps the crust soft for those first crucial minutes — and the loaf leaps upward, splitting along your score line into a proud ear.
Then the lid comes off, and the kitchen changes. The smell of caramelizing crust at dusk, the window fogging, the tick of the cooling stone — this is why people fall in love with baking bread.
Tap the bottom: it should sound hollow, like a drum. The crust shatters; the crumb inside is cream-colored, glossy, and riddled with wild, irregular holes — the fingerprints of fermentation.
The flavor is what no commercial yeast can fake: gentle tang, deep wheat sweetness, a whisper of the week it took to get here. Butter while it's still barely warm. Share it. Then feed the mother again — she's hungry, and there's always a next loaf.
Set your loaves and hydration — the formula adjusts in real time. Levain is held at 20% and salt at 2% of flour weight, the classic ratios.
70% is the easiest place to begin; 75% is forgiving; 80%+ rewards experienced hands with a wilder crumb.
Log each feeding and she'll tell you how she's doing. A mature starter at room temperature likes to eat every 12–24 hours.
Once the mother is alive, every loaf follows the same gentle rhythm. Here's the full arc, Friday evening to Sunday lunch.
Feed the mother so she peaks overnight.
— flour and water rest together.
Add mother & salt. Begin stretch & folds.
Shape the boule. Into a banneton, into the fridge.
Preheat the Dutch oven to 245°C / 475°F.
Score, bake, and let it sing on the rack.
First slice, good butter, no regrets.
Once the plain loaf is second nature, build flavor into it. Fold these in during the final two stretch-and-folds so they distribute evenly without tearing the gluten — except the everything-bagel crust, which goes on the outside.
Rosemary brings piney aromatics, roasted garlic turns sweet and mellow — a world away from raw garlic’s sharpness — and parmesan adds salt and umami. Three different flavor dimensions, so nothing competes.
About 2 tbsp chopped rosemary, 1 head roasted garlic, 100 g grated parmesan.
Fold inThe cheese’s fat tames the chili’s heat, and cheddar’s tang plays with sourdough’s own tang rather than clashing — two kinds of acidity layering instead of fighting.
About 2–3 jalapeños, diced, and 150 g sharp cheddar in small cubes.
Fold inBriny and herbal — basically focaccia flavors baked into a boule. Salt from the olives amplifies everything else around it.
About 150 g pitted kalamata, halved, with 1 tbsp each thyme and oregano.
Fold inSweet-savory, with great textural contrast between crunchy nut and chewy fruit. A natural cheese-board loaf. Swap figs for dried cranberries if you prefer.
About 100 g toasted walnuts and 100 g dried figs or cranberries, chopped.
Fold inSesame, poppy, dried garlic and onion, flaky salt. This one’s purely a crust treatment — nothing gets folded into the dough at all.
Brush the shaped loaf with water, then roll or sprinkle the topping on just before scoring.
Crust toppingHerbaceous and rich — pesto swirls through the crumb in ribbons of basil green, while pockets of mozzarella (or nutty parmesan) melt into something close to a savory galette.
About 3–4 tbsp pesto, swirled in during shaping, with 100 g cubed mozzarella or grated parmesan.
Fold inMediterranean, briny, and bold — three salty, acidic ingredients pointing the same direction instead of competing. Pat everything dry first; loose oil and brine will loosen the gluten.
About 120–150 g total of kalamata olives, crumbled feta, and sun-dried tomato, well-drained.
Fold inSweet, smoky, and deeply comforting — slow-cooked onions turn jammy and mellow, and smoked gouda melts into little pockets of savory depth. Let the onions cool fully before folding them in.
About 1 large onion, caramelized and cooled, with 120 g smoked gouda, diced.
Fold inA rich, cake-like aroma with a chewy artisan crust — cocoa deepens the crumb's color, espresso sharpens the chocolate, and every chunk stays a gooey pocket after baking.
Replace about 10% of your flour weight with dark cocoa, bloomed in part of your water or brewed coffee, plus 100 g dark chocolate chunks.
Fold inThe ultimate breakfast toast loaf — warm cinnamon, toasted pecan crunch, and plump cranberries in every slice. Soak the cranberries first so they don't pull moisture out of the dough.
About 1 tsp ground cinnamon, 80 g toasted pecans, and 80 g dried cranberries, soaked and drained.
Fold inBright, summery, and slightly sweet — lemon zest steeped into the dough water perfumes the whole loaf, and dried blueberries stay plump and jammy through the bake.
Zest of 1–2 lemons added to the dough water, with 100 g dried blueberries folded in at the last stretch-and-fold.
