Flan also known as creme caramel outside of South American countries and the United States, is a custard-based dessert topped with a layer of caramel. Flan originated in Europe and later became very popular in Central and South America. This version of cre'me caramel, retains the custard's lightness, but adds the rich flavor of winter squash for a unique fall or winter desert. It can be served without the carmel sauce or can be made as a pie, by preparing a 9 pie crust (partially baked), then add custard and bake at 450 degrees for 10 min., then lower heat to 325 degrees for 30 min. or until knife comes clean.
