A large, lightweight canvas cloth on which pastry dough can be rolled out. Rubbing flour down into the fibers makes the pastry cloth an excellent nonstick surface. After use, the cloth must be thoroughly cleaned before storing. Otherwise, any fat residue in the cloth will turn rancid and affect the flavor of future doughs.
