Abstract: A device for cooking tortilla shells evenly and to create a U-shape for tacos or bowl-shape for tostadas. For tacos, the device has one shaping member with a top, a bottom, a plurality of vertically disposed peaks from bottom to top, and a plurality of valleys adjacent to each of the peaks. A plurality of apertures are on each of the peaks the purpose of which is to allow full circulation of microwaves on the seated surface of a tortilla shell placed on this shaping member. A two-piece cooking device has two similarly configured rounded shaping members each with a flat top and a downward extending side wall. The top and side walls have a plurality of apertures. A tortilla is placed in between the two shaping members and heated in a microwave oven. Such cooking causes the tortilla shell to retain the bowl-like shape of the two shaping members.
