Winter squashes are best from early fall through winter.
Winter squashes are drier, more fibrous, and much sweeter than summer squashes. The thick, hard shells of winter squashes can not be eaten, but the shells add to the period these squashes can be stored—ranging from 30 to 180 days.
In addition to the sweet flesh which becomes creamy when cooked, the seeds of winter squash can be washed, dried, and roasted either salted or plain.
Winter squash varieties for cooking:
Acorn: somewhat oval and acorn-shaped with a ribbed, dark green skin and orange flesh. The flesh is tender and fine-textured with a flavor that hints of hazelnuts and pepper. To prepare, remove the seeds and bake. You can eat this one directly from the shell. This variety keeps fro 30 to 50 days.
