Also called sweet potato squash, the delicata has a pale yellow skin with medium green striations. Inside, the succulent yellow flesh tastes like a cross between sweet potatoes and butternut squash. The oblong delicata can range from 5 to 9 inches in length and 1½ to 3 inches in diameter. Its peak season is from late summer through late fall. Choose squash that are heavy for their size; avoid those with soft spots. Delicata squash can be stored up to 3 weeks at an average room temperature. As with other winter squash, the delicata is best baked or steamed. It's a good source of potassium, iron and vitamins A and C. See also squash.
