Butternut squash (Cucurbita moschata), also known in Australia and New Zealand as "Butternut pumpkin", is a type of winter squash. It has a sweet, nutty taste that is similar to pumpkin. It has yellow skin and orange fleshy pulp. When ripe, it turns increasingly deep orange, and becomes sweeter and richer. It grows on a vine. The most popular variety, the Waltham Butternut, originated in Stow, Massachusetts, on what is now the Butternut Farm Golf Club.
Butternut squash is a fruit that can be roasted and toasted and also be puréed (to make a soup) or mashed into soups, casseroles, breads, and muffins. It is a good source of fibre, vitamin C, manganese, magnesium, and potassium. It is also an excellent source of vitamin A.
