Try this custard pie with buttercup squash, a sweet, orange-fleshed variety that bakes up luscious, light and surprisingly creamy. Roasted fresh squash has a vibrant color and full flavor, but to save time you can use frozen or canned squash. The pie is best the day it is baked, but much of the preparation can be done in advance. Serve with Ginger Cream. Download a FREE Cookbook with Our Best Fall Recipes!
