Muffin rings
Muffin rings are metal cookware used for oven-baking or griddle-cooking muffins or English muffins. Muffin rings are circle-shaped objects made of thin metal. The rings are about one inch high. Batter is poured into the rings, which are placed on a griddle. The griddle is then baked in an oven. The muffins and the ring are turned over midway through the baking to bake the other side of the muffin.
