A system is provided for producing gluten-free, vegan products at an industrial level. In one implementation, a vat system (200) includes a paddle assembly (202), a blade assembly (206) and steam-lined kettle (210). Whole grains and water are added in a certain order to the vat and heated to cook the mixture. As the mixture is cooking, the blade assembly (206) chops the grain and the paddle assembly (202) mixes the grains and water into a specific texture. The result is a cooked grain product that can be used like a dough in forming a variety of baked goods.
