Mexican foods are cooked similar to how you cook your everyday meals. They can be fried, boiled, and grilled. Mexico has cooked their foods differently in the past.
Long ago, the natives of Mexico did not have ovens like we have today. They would have to cook foods by an open fire pit.
They would hold the foods in iron pots and pans. It cooked like how we grill our foods on the barbeque. Before the Spaniards introduced the iron pots, the Aztecs used to steam and boil foods in two-handled clay pots which were called xoctli. The pot was filled with the food and heated over the fire. Frying foods was a popular way to cook. Many Mexican dishes still use this method.
Today in the present, it is a lot easier to cook Mexican dishes. It takes less time to prepare the foods. If someone wants to make homemade tortillas, there are iron pans that make it easy. Flan can be made simple using spring form type pans. Long ago, it was a long process to make masa, which is a dish that includes a certain type of corn that has to be grinded. Nowadays you can purchase a metal grinder that helps grind the masa.
