Authentic Mexican vs Tex-Mex
Both can be delicious, but they're different cuisines. Knowing which you're eating sets the right expectations:
- Regional Mexican — rooted in indigenous ingredients (corn, beans, chilies, tomatoes, cacao) and regional traditions. Think corn tortillas, complex moles, fresh salsas, slow-cooked meats.
- Tex-Mex — the Texan-American adaptation: hard-shell tacos, lots of yellow cheese, ground beef, chili con carne, nachos, fajitas. Tasty, but a distinct American creation.
Tells of authentic Mexican: corn tortillas (not flour by default outside the north), fresh salsas rather than gloopy 'cheese dip', cuts like carnitas and barbacoa, and toppings of onion, cilantro and lime — not a mound of shredded cheddar.
Corn is everything: masa & tortillas
Corn (maize) is the soul of Mexican cooking, transformed through an ancient process called nixtamalization into masa — the dough for tortillas, tamales and more:
- Corn tortilla — the everyday base, soft and pliable, made fresh at good places.
- Tamales — masa filled and steamed in a corn husk or banana leaf.
- Antojitos ('little cravings') — masa-based street snacks: sopes, huaraches, gorditas, tlacoyos.
- Tostadas — crisp-fried flat tortillas piled with toppings.
Flour tortillas are traditional in the north of Mexico, but corn is the heart of most regional cooking.

Tacos & how to order them
A taco is simply a filled tortilla — but the fillings are a universe:
| Taco | Filling |
|---|---|
| Al pastor | Marinated pork cooked on a vertical spit, with pineapple. A Mexico City icon. |
| Carnitas | Slow-cooked, tender (and crisp-edged) pork. |
| Carne asada | Grilled, chopped beef. |
| Barbacoa | Slow-cooked, traditionally pit-steamed meat (often lamb or beef). |
| Pescado / camarón | Battered fish or shrimp — classic Baja style. |
| Cochinita pibil | Yucatán achiote-marinated pork, slow-roasted. |
- Toppings are minimal and fresh: chopped onion, cilantro, a squeeze of lime, and a salsa — not a cheese avalanche.
- Two tortillas are often served per taco to hold juicy fillings.
- Order a few different kinds to taste the range; tacos are small and shareable.
Moles, salsas and the chili
- Mole — complex sauces of chilies, spices, seeds, nuts and sometimes chocolate, simmered for hours. Mole poblano and the seven moles of Oaxaca are legendary — far more than 'chocolate sauce'.
- Salsas range from fresh salsa verde (tomatillo) and pico de gallo to smoky, dried-chili salsa roja. Heat varies widely — ask.
- Chilies are about flavour as much as heat: smoky chipotle, fruity ancho, fiery habanero. Each brings character (see our dietary guide if heat is a concern).
- Guacamole — avocado, lime, onion, cilantro, chili; simple and fresh, not over-processed.
Regions of Mexican food
- Oaxaca — 'land of seven moles', tlayudas, mezcal, string cheese (quesillo).
- Yucatán — Mayan-influenced: cochinita pibil, achiote, citrus, habanero.
- Puebla — mole poblano, chiles en nogada.
- Mexico City — tacos al pastor, street-food capital.
- Baja California — fish tacos, seafood, a celebrated wine region.
- The North — grilled meats (carne asada) and flour tortillas.

Agave spirits & ordering well
- Tequila — made from blue agave, mostly around Jalisco. Sip good tequila neat; blanco, reposado and añejo mark increasing barrel ageing.
- Mezcal — agave spirit with a signature smokiness, often from Oaxaca. Traditionally sipped slowly, sometimes with orange and sal de gusano.
- Order tip: a margarita is great, but trying a sipping tequila or mezcal reveals the spirit's real character.
- Aguas frescas (horchata, jamaica, tamarindo) are refreshing non-alcoholic classics.
- Seek out cornFresh corn tortillas and masa antojitos signal the real thing.
- Order a taco flightA few fillings to taste the range — al pastor, carnitas, something regional.
- Explore the salsasAsk about heat, and let dairy or rice tame it if needed.
- Try a moleIf it's on the menu and made in-house, it's often the kitchen's masterpiece.
- Sip the agaveA good mezcal or tequila, neat, beats another sugary cocktail.
Real Mexican food is one of the world's great cuisines — deep, regional and built on corn and chili. Look past Tex-Mex shortcuts and order what's traditional. Unsure? Our cuisine finder can point the way.
Frequently asked questions
What's the difference between Mexican food and Tex-Mex?
Authentic Mexican cuisine is rooted in indigenous ingredients — corn tortillas, chilies, beans, fresh salsas, slow-cooked meats and complex moles — and regional traditions. Tex-Mex is the Texan-American adaptation, characterised by hard-shell tacos, lots of yellow cheese, ground beef, chili con carne, nachos and fajitas. Both can be delicious but they're distinct cuisines.
What is mole?
Mole is a family of complex Mexican sauces made from chilies, spices, seeds, nuts and sometimes chocolate, simmered for hours into deep, layered flavour. Famous versions include mole poblano and the seven moles of Oaxaca. Despite the chocolate in some, mole is savoury and far more sophisticated than a simple 'chocolate sauce'.
How do you order tacos like a local?
Order several small tacos with different fillings — such as al pastor, carnitas or a regional speciality — to taste the range. Authentic tacos come on corn tortillas with minimal, fresh toppings: chopped onion, cilantro, a squeeze of lime and a salsa, rather than piled high with shredded cheese.
What's the difference between tequila and mezcal?
Both are agave spirits from Mexico, but tequila is made specifically from blue agave (mostly around Jalisco) and is typically smoother, while mezcal can be made from many agave varieties and has a characteristic smoky flavour from roasting the agave hearts, often in earthen pits. Good versions of both are best sipped slowly and neat.
