Notes

Tip #1 - Oven bake your sweet potatoes, for best results.  If you decide to cook your sweet potatoes with the boiling method add extra flour (¾ cup). Boiled sweet potatoes will have extra moisture.
Tip #2 - Make this casserole up to a few days ahead, for easy baking the day of your celebration.
