1. A Mexican tortilla is a soft, thin and flat unleavened round bread. They are made from corn or wheat flour and baked on a griddle called a comal. Similar to a sandwich when filled with ingredients, a Tortilla can be eaten plain or used as a food wrap to hold other foods, such as meat, poultry, seafood, cheese, beans, onions, and peppers. Some of the common sizes for Tortillas sold in food stores include 6, 8, 10, and 12 inch diameter Tortillas.
2. A Spanish Tortilla, which is quite different from the Mexican Tortilla, is made as a thin omelet containing potatoes mixed with various ingredients, such as onions, peppers, mushrooms, asparagus, and fish.
