Mexican cuisine is primarily a fusion of indigenous Mesoamerican cooking with European, especially Spanish, elements added after the Spanish conquest of the Aztec Empire in the 16th century. The basic staples are native foods, such as corn, beans and chili peppers. Europeans introduced a large number of other foods, the most important of which were meats from domesticated animals (beef, pork, chicken, goat, and sheep), dairy products (especially cheese), and various herbs and spices.
