3 simple ingredients make a great dinner party or holiday dessert. My grandmother made this special treat during the holidays. Incredibly easy! Even the children will be asking for more! The acorn squash can be interchanged with pumpkin, butternut, buttercup, (almost any winter squash) and mangos. Do not handle the squash too much when serving as the meaty part will be soft and can easily me mashed by a heavy handed spoon. The squash is cooked with the skin on. Without it, the squash will be mushy.
