Tostada

Tostada is the name given to various dishes in Mexico and Guatemala which include a toasted tortilla as the main base of their preparation. The name usually refers to a flat or bowl-shaped tortilla that is deep-fried or toasted, but may also refer to any dish using a tostada as a base. It can be consumed alone, or used as a base for other foods. Corn tortillas are usually used for tostadas, although tostadas made of wheat or other ingredients can also be found. Just as stale bread can be made palatable as toast, a stale tortilla can be repurposed as a tostada by frying it in boiling oil until it becomes golden, rigid, and crunchy. Commercial tostadas are similar in taste and consistency to tortilla chips.
