Sopa de castanhas
Before potatoes reached the high plateaus of Trás-os-Montes, chestnuts were the staple, and in villages around Bragança and Vinhais this thick soup is still made in November, when the magusto festivals roast the new crop. Farm versions are cooked with a piece of cured pork; this one is meat-free, built on dried or cooked chestnuts, white beans, onion and a little rice, finished with olive oil. It is sweet, nutty and filling enough for supper. Chef's tip: mash a third of the chestnuts into the broth to thicken it and leave the rest in pieces.
