This chestnut is the fruit of the Longal varietal, grown in the Vila Real and Bragança districts in Portugal. These chestnuts are harvested manually when they fall to the ground, and the use of any mechanical instruments or tools during harvesting is forbidden.
They are reddish-brown with a bright longitudinal stripe on the exterior, and their flavor is intense and quite aromatic. Terra Fria chestnuts can be frozen or processed into jams, syrups, or caldas. They are a common accompaniment to traditional dishes such as fried meat or pork roasts, and they are also to produce bread, cakes, and chestnut flower.
