Vinhais Chestnut Custard Tarts

Pastéis de Nata de Castanha de Vinhais preserve the unmistakable shape of the Portuguese custard tart: a small cup of puff pastry rolled into concentric layers and baked until very crisp. The filling, however, is beige to light brown and denser because chestnut purée or flour enriches the custard. A very hot oven leaves dark caramelised spots across the surface.

Chestnut is more than a decorative flavour. It gives body, earthy sweetness and a velvety texture to the egg-and-milk custard, contrasting with the brittle shell. In Vinhais these tarts appear in pastry shops and at Rural Castanea events alongside puddings, tarts and bolo-rei made from the local crop.
