Abstract: Filled roll dough products, such as pizza rolls, are made with an outer dough shell with an internal filling material. Versus a conventional pizza roll, pizza rolls in accordance with the invention employs a filling material having a lower viscosity upon heating due to the removal of a majority of a viscosity altering additive (e.g., methyl cellulose) used in a conventional filling and an outer dough shell formed with spaced internal ridges which increase the structural integrity of the outer shell while not at all changing the external appearance. While removal of the viscosity altering additive from the filling material increases a blow-out rate for the product, the inclusion of the ridges decreases the blow-out rate to the extent that either a reduction or no significant change in product blow-rates is produced.
