Winter squash comes in many varieties and sizes. Unlike its summer counterparts, winter squash is harvested at a mature age, which makes the skin hard and inedible. The skin, however, is protective and increases its storage life. Winter squash can be stored for 3 months or longer. | Winter squash comes in many varieties and sizes.
