Mexican cuisine makes most of us think of assertive spices; mostly chilies and cumin. This combination of spices is one, which is a perfect representative of the country’s culinary history; an ingredient, which came from the old world with the Spanish and one, which has been a central part of Mexican food for thousands of years.

Chilies of all sorts have been in use as spices for thousands of years in Mexico; peppers of all varieties (as are tomatoes and potatoes, which are related members of the nightshade family) are native to the Americas and these vegetables were one of the dietary staples in Mexico before the arrival of Europeans, as they are to this day.

Jalapenos are the most familiar of these peppers to people in the US. They are commonly used in salsas and pickled for use as a condiment as well as diced for use fresh. The Serrano pepper, a smaller, slightly hotter pepper is also seen relatively often in the US. Many Mexican food recipe are nearly unthinkable without these fiery vegetables. Other peppers such as pasillas and anchos are commonly dried and then ground; others are smoked, such as chipotle peppers (which are actually smoked jalapenos).

Some of the Mexican culinary herbs, which are native to the country, include epazote, culantro, and Mexican oregano, all of which are very important to various Mexican recipes. Used very often in Mexican and Caribbean cooking, culantro is largely unknown in the US and hard to find other than in Mexican groceries. Its flavor, however, is similar enough to cilantro that this herb may be substituted if you cannot find the real thing in your area.

Do not let the name fool you - Mexican oregano may taste something like a more assertive version of the familiar Greek oregano, but this herb is actually a close relative of lemon verbena. Its flavor is an important component in a number of Mexican dishes, but you can substitute the old world herb if needed. However, Mexican oregano is becoming easier to find. You can usually purchase this herb from specialty spice shops as well as Mexican groceries. It is usually used dried, just like Greek oregano.

Epazote, however, has no real substitute. It tastes a little like tarragon, but its flavor is uniquely its own. This herb is commonly used when cooking Mexican bean recipes, especially black beans. However, you can safely omit this herb in your Mexican recipes if it is not available. Look for epazote in the produce aisle of Mexican groceries; if you cannot find fresh epazote, you may be able to find it dried in the spice section.

While we often think of cumin when we think of Mexican food, this spice is one, which came across the Atlantic with the conquistadors, being a common herb in Spanish cooking and other Mediterranean cuisines. However, cumin works so well with many of the ingredients native to the new world that this spice quickly became an integral part of many Mexican recipes.

You might say that Mexican food is among the world’s first fusion cuisines, with its blending of old world and new world flavors. Using ingredients from both Europe and the Americas, Mexican cooks created something unique, new and distinctively Mexican. It is a cuisine which has a flavor all its own and thanks in part to Mexican spices, it has become popular in nearly every part of the world.
