Grapefruit or mixed fruit marmalade will work just as well as the orange marmalade called for in the recipe. Serve the casserole with honey or pancake syrup warmed with orange rind and a splash of orange juice (add one teaspoon rind and two tablespoons juice per 1/2 cup syrup). This easy casserole can be assembled in less than 15 minutes and stored in the refrigerator overnight.
