Try this the next time you make Sweet Potatoes instead of Potatoes.
If using raw sweet potatoes, pare and cut into slices 1/2 to 3/4 inch thick. Place in a saucepan and add 1 cup of water and cook until tender. If using canned, drain.
Using 1 Tbls of butter, grease a 9 X 13 X 2-inch baking pan and add the sweet potatoes and cherries.
Combine the remaining ingredients except the marshmallows in a saucepan and cook until you have a thin syrup. Pour the syrup over the sweet potatoes and cherries. Bake in a 350 degree F. oven for 30 minutes or until the syrup is thick. Just before serving top with the marshmallows and return to the oven to brown.
