Country loafsourdough, the wild-yeast leaven

The whole-leaven loaf: no commercial yeast, no sugar, a stiff levain and a wet dough doing all the rising. The flavour is the point — the levain carries a mild tang and the deep, toasty, almost nutty note that a commercial dough can't, because a living culture works on the crumb over hours while a packet yeast only puffs it. The dough logic is the same as the rest of the site's breads — the gluten develops in gentle folds, and the shape is the seam and score — but the schedule is a day, not an afternoon.

Total

~1 day, most of it proving

Equipment

• A 1.2 L mixing bowl for the levain, and a larger one for the dough
• A banneton (boulle proofing basket) or a floured bowl with a towel, roughly 24 cm across
• A Dutch oven (cast-iron pot with a lid) for the bake — or a tray and a second pan for the steam

Ingredients

• 100 g strong white bread flour, for the levain — the two-day starter, kept at room temperature
• 100 g water, for the levain
• 350 g strong white bread flour, for the dough (a whole-grain loaf runs more brown; the levain stays the same)
• 280 g cool water, for the dough (80% hydration — wetter than the baguette, and the gluten builds in the bowl, not on the bench)
• 10 g fine sea salt
• 150 g of the levain, ripe and doubled, for the dough
• Rice flour, for the banneton, and for the peel to turn the loaf out onto

Method

1. The levain, the day before. Mix the 100 g of starter with 100 g of flour and 100 g of water well, cover, and leave at room temperature. It's ready in 4–8 h — doubled, domed, and smelling like ripe fruit and a little vinegar. That's the wild yeast doing the rising the packet yeast would have done, and it takes the whole day because the culture is working, not just acting.
2. Autolyse. Mix the 350 g of flour with the 280 g of water until no dry flour shows, and rest, uncovered, 1 h. No salt yet — the flour starts its gluten build on its own, and the salt, which tightens and slows the gluten, waits.
3. Fold in salt and levain. Add the levain and the salt, and work them in with a little water, a little more if the mass is too stiff. The dough will be slack, sticky, and almost liquid at the edges. That's correct — the wetness is the open crumb, and the structure is coming from the folds, not from kneading.
4. Bulk ferment, by the fold schedule. Rest, covered, 30 min. Then: lift and fold each side of the dough up and over the opposite one — four corners, a 10 s break, turn the bowl a quarter-way, repeat. Four sets total over the first 2 h, after which the dough is smoother and less sticky, and the gluten is up. Rest, covered, a further 2–3 h until the dough has visibly risen and jiggles like a set jelly. The jiggle test is the proof check: poke the centre gently; if the dent springs back slowly with a little resistance, it's alive and ready to shape. If it springs back fast and tight, it needs more time.
5. Pre-shape and rest. With a bench scraper, gather the dough into a rough round on a floured bench. The seam — the underside — goes down. Rest, covered, 20 min.
6. Shape. Into the final boule: cup the dough, tucking the edges under and around the base to build tension on the top surface, and turn it seam-down into the rice-floured banneton. The seam — the gathered underside — is the whole shape, the same gathering the dumpling runs; the top holds its tension, and it keeps it through the final proof and the bake.
7. Final proof. The banneton goes in the fridge, 12–16 h, or, for a same-day loaf, at room temperature for 1.5–2 h until it passes the jiggle test again. The slow, cold proof is where the flavour goes in: the levain works on the crumb over hours, and the tang and the depth are the price of a schedule you can't rush.
8. Bake. Preheat the Dutch oven (uncovered) at 250 °C / 480 °F for 30 min. Turn the loaf out of the banneton onto a floured peel, score the top with a single deep slash — the oven spring pushes out the way the cut goes — and slide it into the pot. Lid on, oven at 230 °C / 450 °F, 20 min. Lid off, 10–15 min more, until the crust is a deep, honest brown. Rest on a rack 30 min before cutting — the crumb is still setting, and a rushed slice tears it.

Common failures

Variations

• The whole-grain loaf. Half the white flour for a wholemeal or rye — the levain stays exactly the same, the hydration drops a little (the whole grain holds more water), and the crumb reads darker and denser. The flavour is the point.
• The seeded loaf. A 50 g scatter — sunflower, sesame, flax — folded into the dough at the last fold step, and a handful on top before the final proof.
• The seeded, oil-soaked sheet. The focaccia, with the same levain in place of the packet yeast — the wild culture doing the rising, the pan doing the finishing.
