Pumpkins are an orange/yellow member of the squash family, commonly used in pies, loafs and curry. They are also notable for their non-culinary use in Jack-O-Lanterns.
Typical spicing for sweet pumpkin preparations is brown sugar, nutmeg, cinnamon, and cloves.
For savory preparations, prepare as squash -- typically roasted -- and cut into cubes or mash. Diced pumpkin is a good addition to an aromatic curry.
