Select a toupin or tall earthenware pot. Lay a thick layer of stale bread slices across the base. Distribute half the cabbage, turnips, carrots, potatoes, onions, and garlic over the bread. Add a second layer of bread slices, then the remaining vegetables. Nestle the confit duck leg or salted pork among the vegetables so that it is submerged when liquid is added. The layering is complete when the pot is filled to within 5 cm of the rim.

Pour the water or whey over the layered contents, ensuring all bread and vegetables are covered. Place the pot at the edge of the fire — or over the lowest possible heat — and bring to a very gentle simmer. The surface should barely tremble. Maintain this throughout.

Simmer undisturbed for 2 to 3 hours. This is where the dish lives or dies: the bread must dissolve completely into the liquid, thickening it to an extremely dense, porridge-like consistency — the trempe or miquel. If the liquid remains thin and the bread retains its structure before the two-hour mark, the heat is too low or the bread was not stale enough. The correct result is a mass so thick a spoon dragged across the surface leaves a channel that closes slowly.

Remove the confit leg or salt pork. Shred the meat and return it to the pot, discarding any bone. Taste the soup: it should carry the depth of the bread, vegetables, and enriched fat with no single element dominant. Adjust salt.

Place a thick slice of additional stale bread in the base of each bowl. Ladle the thick soup over it, creating a further layer of bread at varying degrees of sogginess beneath the trempe. Serve with a spoon — the only utensil required.

When the bowl is nearly empty — the last centimetre of broth remaining — pour 30 ml of Madiran or Béarn rouge into the bowl and tilt it to the lips to drink directly. This is faire chabrot. The wine should cut through the richness of the bread-fat broth with a clean tannic finish: the ritual is complete when the bowl is empty.
