What is winter squash? Winter squash is harvested and eaten in its mature fruit stage when the skin has hardened into a tough rind. The tough rind makes it possible for the squash to be stored for use during the winter months.
Winter squash includes acorn, butternut, delicata, kabocha, pumpkin, and spaghtti, etc. Generally, winter squash is cooked before being eaten, and the skin or rind is not typically eaten as it is with summer squash.
