Biscottini di Prosto, Traditional butter cookies in Piuro, Italy.

Biscottini di Prosto are traditional butter cookies from Piuro made with flour, sugar, and a generous amount of butter that creates a delicate, crumbly texture. The dough is formed into cylinder shapes and then sliced before baking to achieve their distinctive character.

The recipe dates back over a century, when the biscuits were made at home for holidays, above all the Feast of the Assumption on 15 August. On those occasions the dough was baked in the village's only oven, the Mulino of the Del Curto family, next to the church of Prosto. The biscuits are now a traditional agro-food product of Lombardy.

In chiavennasco dialect the biscuits are called biscotìn de Prost. They were once baked at home for the Festa Patronale dell'Assunta on 15 August, in the only local oven, that of the Del Curto family by the village church. Today they are served at the end of meals in the crotti of Valchiavenna.

The biscuits are homemade and need only flour, sugar and plenty of butter, so they can easily be baked at home. In Valchiavenna they are served at the end of the meal in the area's crotti, the stone cellars used as taverns.
