I just diced and roasted 4 large butternut squashes before mashing to a puree and putting into freezer bags. I like using the freezer but am always worried if the power is to go out. Anyone know if I can put them in bottles to preserve them in the pantry? I'd probably have to pressure cook them, just like pumpkin but have never done it before.
Also, I heard that lightly rubbing vegetable oil on the skins of the butternut squash will allow them to keep longer in a cool dry place without doing any else to them (deters mold?). Is this true?
