This recipe was on a sticker on the cute mini-acorn squashes I got today at the store, and turned out really well (especially since I was using Melanie’s homemade marmalade):
Cook acorn squash according to standard operating procedures (cut in half, remove seeds, put face down on cookie sheet in 400 degree oven for around 30 minutes until very soft when poked with a fork)
Flip the squashes so that the inside is facing up. Put a dollop of orange marmalade and a dollop of butter in the center of each half squash. Place under broiler on high until somewhat browned.
Enjoy!
