Steps 1 & 2

If you planted squash, and instead got squatermelons, it means you had squashes and melons growing near each other and your bees enjoyed both. That's my theory, anyway. Some of the squashes on my spaghetti squash vine are whitish-yellow and pure squash, some are green and thump/smell/taste like mild watermelon, and some are a little of both - speckled green on the outside but with a hard winter squash shell and easily stranding flesh. My daughter calls them squatermelons and they taste just fine. But how to cook? Easy...

Wash your squatermelon and wrap the stem in foil.

 Put it in the oven and set heat to 400 degrees for 1-1/2 hours.
