US Patent 7147881 Method for producing a composite dough-based product

A method for making a composite dough by preparing a wheat dough by mixing wheat flour, fat and water in a manner effective to form an homogeneous and cohesive gluten structure followed by sheeting the dough into a sheet; separately preparing a non-wheat dough by mixing a non-wheat flour and water to form a homogeneous mass of dough that is sufficiently cohesive to be subsequently handled; assembling the wheat dough with the non-wheat dough; and laminating the wheat and non-wheat doughs to form a composite dough.
