It started in a flat with bad heating, in a jam jar, from nothing but rye flour and tap water. Eleven years later it has survived two house moves, one holiday I should not have taken, and a winter that nearly finished it.

People ask what makes it special. Nothing does — that is the point. Feed a jar of flour and water for a decade and it becomes specific to your kitchen, your flour, your hands. Ours smells faintly of apples. I have no idea why.

This is the recipe we actually use, not a simplified one. It takes two days because it has to; the flavour comes from the overnight rest, not from anything you do with your hands.

Friday

1. Mix the dough — flour, water, milk, a little sugar, salt, yeast. Knead briefly. Rest one hour, then fridge overnight.
2. Beat the butter into a flat square between two sheets of paper. Fridge.

Saturday morning

1. Lock the butter into the dough. One double fold, rest thirty minutes cold.
2. Two more single folds, thirty minutes cold between each.
3. Roll, cut triangles, shape. Prove two to three hours — they should wobble, not spring.
4. Bake hot, then drop the heat. Twenty minutes total.

Eat one standing up, before the shop opens. That is the baker's fee.

Lamination is not difficult. It is unforgiving, which people mistake for difficult. Everything that goes wrong goes wrong for the same reason: the butter got warm.

The three failures

1. Butter too cold: it shatters instead of spreading, and you get shards rather than sheets.
2. Butter too warm: it merges into the dough and you have made brioche by accident.
3. Rushing the rest: the gluten fights back and the dough shrinks the moment you turn your back.

Between those three is a window of a few degrees. Work inside it and lamination is just folding.

The sourdough gets the photographs. The bun gets the lunchboxes, the last-minute guests, the Tuesday that got away from you. It is soft, quick, endlessly adaptable, and completely unbothered by your ambitions.

Respect the bun. It has fed more people than any showpiece loaf ever will.

Forget the gadgets. Bread has three dials: how much salt, how much time, how much heat. Learn what each one does and you can bake anything; ignore them and no amount of equipment will save you.

Salt slows and seasons. Time builds flavour and structure. Temperature decides the crust. That is the whole science, minus the parts you can feel with your hands.

The last week of autumn is the best week in the bakery. The squash is sweet, the walnuts are new, the apples are on their way out and taste like they know it. Everything wants to be baked at once.

Bake the walnut loaf. Bake the apple thing you never write down. Bake more than you can eat, and give the rest away — that is what the season is for.

A starter is a pet that eats flour and holds a grudge about temperature. In winter, a cold kitchen slows it right down, and a slow starter makes a flat loaf.

We keep ours near the oven, feed it a touch more often, and use a little warm water in the mix. Treat it well and it will outlive the winter — ours has seen eleven of them.

This is the loaf the shop is built on. It asks for almost nothing but your patience, and it gives back more than any recipe with twice the steps.

The method

1. Friday evening: feed the starter and go to bed.
2. Saturday morning: mix flour and water, rest one hour, then add starter and salt.
3. Saturday: four gentle folds across four hours. Shape at night, into the fridge.
4. Sunday morning: bake hot, lid on for twenty minutes, lid off for twenty more.

Two days, four minutes of actual work, one loaf that will ruin supermarket bread for you forever. That is the trade, and it is a good one.
