Mexican Cuisine: Corn, Chillies and the 6 Best-Known Dishes

Mexican cooking is inscribed on the UNESCO list of intangible cultural heritage, a rare recognition for an entire cuisine. The reason is that it is not merely food — it is an agricultural and cultural system thousands of years old, built on the milpa: growing corn, beans and squash together in the same field.

The core dishes

1. The tortilla — the base of everything

The original corn tortilla is made from corn treated with lime, a process called nixtamalisation. That treatment releases the vitamin B3 in corn and makes it available to the body. Without it, a corn-dependent diet causes malnutrition, and ancient civilisations discovered this empirically.

Wheat tortillas appeared in the north after the Spanish, and they are the basis of burritos and quesadillas.

2. Tacos

A real taco is a small soft corn tortilla — not a crisp shell — with meat, onion, coriander and lime, and nothing else. The crisp shell is an American invention.

3. Enchiladas

Tortillas rolled in chilli sauce with cheese and baked. The detail that prevents tearing: pass each tortilla through hot oil for ten seconds before rolling.

4. Quesadillas

Tortilla and cheese on a griddle. The common mistake is high heat — the tortilla burns while the cheese stays solid. The correct approach is medium-low heat and three to four minutes a side.

5. Guacamole

Avocado mashed with lime, onion, coriander and chilli. The lime is not only for flavour — its acidity slows oxidation so the avocado does not blacken quickly.

6. Pozole

A soup of large corn kernels, hominy, with meat, served with radish, lettuce, oregano and lime on the side. A celebratory dish made for occasions.

Chilli varieties — not all of them are hot

Mexico has over a hundred chilli varieties, each with its own use. Ancho (dried poblano) is sweet and smoky with almost no heat; chipotle (smoked jalapeño) is moderately hot with a strong smoky flavour; and habanero is very hot and fruity.

Dried chillies are soaked in hot water for twenty minutes and blended into a paste — the base of mole and enchilada sauces.

Mole — the legendary sauce

A complex sauce combining dried chillies, chocolate, nuts and spices, sometimes running to forty ingredients. The chocolate is not there for sweetness: its bitterness balances the chilli heat and adds depth.

Making it traditionally takes a full day, and in Mexico it is sold ready-made as a paste to be dissolved in stock.

The difference between Mexican and Tex-Mex

Tex-Mex was born in Texas from the fusion of Mexican and American cooking. Its markers: a lot of yellow cheese, heavy cumin, refried beans, and the crisp taco shell — none of which exist in traditional Mexican cooking.

That is not a criticism — Tex-Mex is a cuisine in its own right with excellent recipes. The point is simply to tell them apart.

Ingredients worth buying

• Dried chillies (ancho and chipotle): the base of the sauces, and they keep for months.
• Fresh coriander: a core ingredient by the handful, not a garnish.
• Limes: squeezed over almost everything.
• Mexican oregano: different from Mediterranean — sharper and closer to citrus.
• Corn tortillas: or masa harina to make them at home.

How a meal is ordered

The main Mexican meal is comida, eaten between two and four, and it consists of soup, then rice or pasta, then the main course with beans and tortillas, then a light dessert.

The salsas are put on the table and each person adds their own — they are not mixed into the food.

Common mistakes

• High heat for quesadillas: the tortilla burns while the cheese stays solid.
• Not passing tortillas through oil for enchiladas: they tear as you roll them.
• Mashing guacamole smooth: the texture should keep some chunks.
• Burning dried chillies: seconds in the oil, or they turn bitter.
• Using Mediterranean instead of Mexican oregano: a completely different flavour.

Where to start

Quesadillas are the quickest entry — ten minutes and simple ingredients. Then guacamole (no cooking), then tacos.

Enchiladas take more preparation but the result suits a dinner party. Mole comes last, because it takes a long time and many ingredients.

Beans in Mexican cooking

Beans are not a side dish in Mexico — they are a primary protein eaten daily. The traditional method: simmered plain with only onion and garlic, then half mashed in hot fat (frijoles refritos) with the rest served in their broth.

The common mistake: adding salt at the start of cooking. Salt toughens the bean skins and lengthens the cooking considerably. The rule: salt in the last fifteen minutes.

Mexican drinks

Aguas frescas are fruit drinks diluted with water and lime, the best known being horchata (rice, cinnamon and milk), jamaica (hibiscus) and tamarindo. All are served with the food rather than before it.

Mexican hot chocolate is whisked with a wooden molinillo until it foams, and made with cinnamon and sometimes chilli — and chocolate is Mexican in origin, long before it reached Europe.

Lime on everything

If you take one habit from Mexican cooking, make it squeezing lime over everything: on tacos, on soup, on grilled corn, even on potatoes. The acidity lifts the flavour and balances the fat, and it is the cheapest, fastest improvement you can make to any dish.
