Olla Ferroviaria de Burgos

Olla Ferroviaria de Burgos belongs to the railway line more than to a polished dining room: chickpeas, pork, chorizo, vegetables, and time, cooked in an iron olla while the men of La Robla worked the track. This is Castilian spoon food, cocina de cuchara, made to be a full meal from one pot, not a little bowl before something finer. The chickpeas must stay whole, the pork must give itself up, and the broth should come out deep enough to stain the spoon.

The method that decides it is the slow start and the steady heat. Soak the chickpeas overnight, start them in hot water so they don't seize, then keep the pot at a small, patient bubble. A hard boil breaks the chickpeas and makes the broth cloudy and rough. The sofrito, the slow onion base, goes in near the end after it has turned dark gold and sweet with pimentón. Rush that, and the pot tastes thin. There it is, the whole argument.

If you don't have an iron railway olla and a bed of coals, use a heavy Dutch oven on the lowest heat your stove can hold. No hace falta haber pisado España. If Burgos morcilla is hard to find, use a good Spanish morcilla de cebolla; if not, leave it out before you use a sweet breakfast sausage and call it the same thing. Chickpeas matter here, so buy good dried ones and pésalo, no lo adivines. Siempre sale, si lo sigues.
