Butternut squashes are different from their summer squash relatives because they have much tougher skin that protects their firm, yellow-orange flesh. They’re self-reliant too as they don’t need to be refrigerated and can be stored in a cool, dark place for several weeks.
When choosing a butternut squash, first pick one up. It should be heavy for its size, have firm skin and be free of bruises. You’ll want to avoid squashes that have brown frostbite scars as this can affect texture and longevity. Also, avoid squashes with punctures or cuts which can lead to bacteria and mold.
