Abstract
Abstract Tortillas are placed on a flexible, pliable, perforated web made of woven metal. A plunger folds over the tortilla, folding the tortilla and the metal web, and the combination wherein the tortilla is fried crisp in the folded position, thus forming it into a taco shell. Thereafter, the plunger with the taco shell theron is unfolded from the metal web and the fat drained and shaken from the shell and the shell dropped from the plunger.
