Roasted chestnuts are a warm, nutty snack or ingredient made by heating chestnuts until their shells crack and the sweet, starchy flesh inside becomes tender. They are a classic winter treat in many European and Asian cultures, often enjoyed straight from the shell or used in stuffings, soups, and desserts. The primary ingredient is simply fresh chestnuts, sometimes lightly salted.
Chestnuts are unique among nuts for being low in fat and high in complex carbohydrates, providing a good source of dietary fiber, vitamin C, and minerals like manganese and copper. A typical serving contains around 200-250 calories, making them a filling, energy-dense snack.

Unlike most nuts, which are high in fat, chestnuts are primarily composed of starch, giving them a texture more similar to a potato when cooked. They are one of the few nuts that contain a significant amount of vitamin C, which can survive the roasting process.
