Grind flour and bake bread

Rub grain between two stones into flour, catch wild yeast in a jar, and bake your first real loaf in the clay oven.

Grain in a jar is wealth; bread is that wealth made into dinner. You do three things people have done for ten thousand years: crush the grain between stones into flour, wake up wild yeast — invisible living things on the grain and in the air that make dough puff up — and bake the risen dough in a hot oven. The yeast takes about five days to catch; everything after is quick.

Your first loaf will be heavy, a bit rough, and the best thing you have ever eaten.

You need

• Clean, dry grain — wheat makes the puffiest bread; barley and corn make flatter, denser loaves.
• Two hard stones: a wide flat or dish-shaped base stone, and a smooth rounded rubbing stone that fits your hand. Hard stone only — granite or other tough rock that doesn't scratch easily. Soft, crumbly stone sheds grit into your flour and wears your teeth down over the years.
• A jar for the starter, plus cloth to cover it.
• Water — clean drinking water.
• Salt if you have it — bread works without, but tastes flat.
• A bowl, and cloth for covering dough.
• Your clay oven, plus dry firewood — enough for a 1–2 hour fire.

Steps

1. Grind. Put a small handful of grain on the base stone. Press and rub the hand stone over it, away and back, adding grain a little at a time. First passes make cracked grain; sweep it up and grind again until it is powder. Expect an hour or more of grinding per loaf at first — grind over several days and store the flour dry.
2. Start the wild yeast (day 1). In the jar, mix a small handful of flour with the same amount of water into a thick paste. Cover with cloth — air in, flies out. Keep it comfortably warm (roughly 20–25 °C).
3. Feed it daily (days 2–5). Once a day, throw away half, then stir in a fresh half-handful each of flour and water. By day 3–5 it should bubble and smell pleasantly sour, like yogurt or beer. When it doubles within a few hours of feeding, it is ready. This living paste is called a starter.
4. Mix the dough (evening). In the bowl: about two double-handfuls of flour, a fist-sized blob of bubbly starter, a big pinch of salt, and enough water to make a soft, sticky mass — roughly 2 parts flour to 1 part water by volume.
5. Knead: press, fold, and turn the dough for about 10 minutes until it goes from shaggy to smooth and stretchy. Cover it and leave it somewhere warm.
6. Let it rise until it grows about half again to twice its size. With wild yeast this is slow — 4–12 hours, so overnight is perfect.
7. Shape and rise again. Punch the dough down gently, shape it into a round, set it on flour-dusted cloth, cover, and let it puff up again, 1–3 hours.
8. Fire the oven. Burn a good fire in it for 1–2 hours until the inside walls turn from black soot to whitish — that color change is your thermometer. Rake out all coals and ash, wipe the floor with a damp (not wet) rag on a stick.
9. Bake. Slide the loaf onto the hot oven floor, close the door, and leave it about 40–50 minutes. Done test: the crust is deep brown and the loaf sounds hollow when you tap its bottom.
10. Wait half an hour before cutting — the inside is still finishing as it cools. Save the starter jar and keep feeding it daily; tomorrow's bread is already alive in there.

Watch out

• Grit in the flour means your stones are too soft. Change stones. A lifetime of gritty bread wears teeth flat.
• Starter gone wrong: pleasant sour smells are fine, but pink, orange, or black streaks, fuzzy mold, or a rotten smell mean throw it all out, wash the jar with boiled water, and start again. Never eat a doubtful starter.
• Dough that never rises: the room is too cold or the starter too young. Move it somewhere warmer and give it more hours; feed the starter a few more days before trying again.
• Burnt outside, raw inside means the oven was too hot. Let the fired oven stand 15–30 minutes longer before loading, or bake a flatter loaf.
• Steam burns when opening a hot oven — open it away from your face.
• Damp flour molds. Grind only what you'll use within a few weeks; store it dry, sealed, and cool. Whole grain keeps for years; flour does not.

How it works

Grinding breaks the kernel open so water and yeast can reach the starch. The wild yeasts eat that starch's sugars and breathe out gas; wheat dough holds a stretchy web (gluten) that traps the gas as tiny bubbles. The oven's heat sets that foam solid — bread is simply a cooked sponge of grain, air, and time.
