There are actually few similarities between Mexican food and Spanish food. One example would be tortillas. They are used in the cooking of both cultures, although they are a staple in Mexican food and are used more sparingly in Spanish cuisine. Spanish food tends to be more Mediterranean. They use a large amount of shellfish. Potatoes, eggplant, and olive oil while Mexican dishes tend to use large amounts of chili peppers and tortillas. Mexican food tends to be spicier overall. Mexican dishes are more often served one per individual, while Spanish tapas (appetizers) are made for sharing. There is also more finger food in Mexican dishes. Seasonings between the foods of the two cultures tend to be different as well. The main example of this would be cilantro which is used in many Mexican dishes but seldom in Spanish ones (as fresh cilantro is quite difficult to find in Spain).
