It's not really a recipe, just a method I always use.
2-3 large cans yams, drained
about 1/2 stick butter
about 1/2 cup brown sugar
1/2 tsp. cinnamon
1/4 nutmeg
1/4 cup granulated sugar
marshmellows
Okay. Drain the yams and pour into a baking dish. Cut about 1/2 stick butter into small cubes, place the cubes all over the yams. Spinkle all the rest of the ingredients all over the yams. cover with marshmellow. Bake at 350 for about 30 or until marshmellow melt and are golden brown.
