1 big yam or sweet potato. Peel, chop, cook. Mash with whatever you choose to your taste: maple syrup, butter, salt , pepper, brown sugar.
I had whipped 1 extra large egg to mix in the stuffing and used 1 teaspoon of it in the mashed mixture plus 1 tablespoon of flour.
Pressed dough in cupcake wrapper placed in muffin tin, added 1 mini marshmallow in the middle just for effect.
