Halloween pumpkins, often called jack-o'-lanterns, are a popular symbol of the Halloween holiday. Traditionally, people carve faces or designs into pumpkins, which are then illuminated from within by a candle or light. This practice dates back to ancient Celtic festivals, where turnips were originally used before pumpkins became the favored choice in North America. The pumpkins used for Halloween are typically larger varieties, such as the Connecticut Field pumpkin. These pumpkins are harvested in the fall, making them readily available for decoration. In addition to carving, many people enjoy using pumpkins for cooking, baking, and making pumpkin spice treats during the Halloween season.
