Tostada

Tostadas are various dishes in Mexican and Guatemalan cuisine based on toasted tortillas. They are generally a flat or bowl-shaped tortilla that is deep-fried or toasted, but may also be any dish using a tostada as a base. They 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 are also 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.
