Abstract
Abstract An edible food container is provided with two different fatty coating layers including a top glaze that is free of sugar. A prima coat has a higher setting temperature than the top glaze. Hydrophobicity increases from the prime coat to the top glaze. Solids can be added to the top glaze and the container can be made from a sugar free baked dough. Other variations are also disclosed.
