Butternut Squash is a type of pumpkin or winter squash that grows on a vine. It has a sweet, nutty taste similar to that of a pumpkin. It has tan-yellow skin and orange fleshy pulp with a compartment of seeds in the blossom end. When ripe, it turns increasingly deep orange, and becomes sweeter and richer. It is a good source of fibre, vitamin C, magnesium, and potassium; and it is a source of vitamin A.
