  • Patent number: 4173926
    Abstract: A holder for forming and cooking a tortilla into a pie shell. The holder includes nestable apertured pans which are initially vertically separated to receive a tortilla to be cooked. The holder is then dipped into hot oil and the pans moved towards each other to form the pliable tortilla into a pie shell shape. Thereafter, the holder remains within such frying pan until the tortilla is cooked to a firm consistency. The holder may also be utilized with regular pie crust dough rather than a tortilla.
