Pumpkins are winter squashes,
but not all winter squashes are pumpkins!
In the fall many wonderful varieties are available. Squash is native to the New World, and some species have been cultivated for more than 9,000 years.
Roasting is one of the best cooking methods for winter squash, it concentrates the sweetness of the flesh more than any other technique.
Steaming is another option which adds moisture to the drier-fleshed varieties such as Kabocha. Avoid boiling, it tends to yield waterlogged, bland, or tasteless flesh. As a general rule, it ‘s better to slightly overcook squash rather than undercook it, with the exception of spaghetti or Orange squash; overcooking those varieties makes their signature noodle-like strands gummy and mushy.
