Mexican Food Myths Debunked: What British Diners Get Wrong

Time to Set the Record Straight

Mexican food is one of the world's great cuisines, recognised by UNESCO as an Intangible Cultural Heritage of Humanity. Yet in the UK, it remains one of the most misunderstood. Decades of Tex-Mex influence, supermarket dinner kits and fast food chains have created a version of "Mexican food" that bears little resemblance to the real thing.

This is not about food snobbery. If you enjoy a Taco Bell or an Old El Paso kit, that is perfectly fine. But if you have ever dismissed Mexican food as "just spicy" or "basically the same as Tex-Mex," you are missing out on one of the most diverse, sophisticated and historically rich cuisines on the planet.

Myth 1: Mexican Food Is Always Extremely Spicy

The reality: Chiles are fundamental to Mexican cuisine, but heat is just one dimension of their use. Many Mexican dishes are not spicy at all. Chiles are used primarily for their flavour, which ranges from sweet and fruity (ancho) to smoky and complex (chipotle) to earthy and mild (pasilla). The heat level is adjusted to personal taste, and many traditional dishes are genuinely mild.

Dishes like mole negro get their complexity from chiles, chocolate, nuts and spices, but are not especially hot. Tamales, quesadillas, pozole blanco and many soups are gentle on the palate. Even in Mexico, not everyone eats food at scorching heat levels.

What to try: Start with dishes like quesadillas, enfrijoladas or tamales to experience Mexican flavours without significant heat.

Myth 2: Hard-Shell Tacos Are Mexican

The reality: The crunchy, U-shaped taco shell was invented in the United States. In Mexico, tacos are served on soft corn tortillas, always. The closest Mexican equivalent to a crunchy taco would be a tlacoyo, flauta or tostada, but these are different preparations entirely.

The Old El Paso taco kit that sits in every British supermarket is a perfectly tasty product, but it is American-style Tex-Mex, not Mexican. If you have only ever eaten tacos from a kit, you have never really eaten a taco.

What to try: Make or buy soft corn tortillas and fill them simply with well-seasoned meat, salsa, chopped onion and fresh cilantro. That is a real taco.

Myth 3: Sour cream Goes on Everything

The reality: British Mexican restaurants have a habit of putting a dollop of sour cream on every single dish. In Mexico, cream (crema) is used, but it is a different product: thinner, tangier and used as a drizzle rather than a blob. And it definitely does not go on everything.

Mexican crema is closer to crème fraîche than to sour cream. It is used to cool down spicy dishes, to add richness to enfrijoladas and to drizzle over tlacoyos. But you would never see it on a taco al pastor or alongside barbacoa.

UK alternative: Mix equal parts sour cream and heavy cream for a closer approximation of Mexican crema.

Myth 4: Burritos Are a Mexican Staple

The reality: As discussed in our tacos vs burritos guide, burritos are primarily a dish from Mexico's far north and from Mexican-American cuisine. Most Mexicans outside the border states rarely eat burritos. The giant, overstuffed burrito with rice, beans, meat, cheese, guacamole and sour cream is an American invention.

This does not mean burritos are bad. They are delicious. But calling them "authentic Mexican food" is like calling chicken tikka masala "authentic Indian food." They are a diaspora creation, not an original.

Myth 5: Mexican Food Is Unhealthy

The reality: Traditional Mexican cuisine is remarkably well-balanced and nutritious. The foundation of corn, beans and chiles provides complex carbohydrates, complete protein (when corn and beans are eaten together) and essential vitamins. Fresh salsas are loaded with vitamins C and A. Avocados provide healthy fats.

The "unhealthy" perception comes from Americanised Mexican food, which tends to be heavy on cheese, sour cream, fried shells and oversized portions. A traditional Mexican meal of grilled fish tacos on corn tortillas with fresh salsa and a bean side is genuinely one of the healthiest meals you can eat.

Myth 6: Chili con carne Is Mexican

The reality: Chili con carne as we know it in Britain (ground beef, kidney beans, tomatoes, cumin) is a Texan invention with no direct equivalent in Mexican cuisine. Mexicans do not eat it. The dish emerged in San Antonio, Texas, in the 19th century and evolved into its modern form in the American Southwest.

Mexico does have stews that combine meat and chiles, such as birria, carne con chile colorado and various guisados. But they are distinct preparations with different techniques and flavour profiles.

Myth 7: Nachos Are a Mexican Dish

The reality: Nachos were invented in 1943 by Ignacio "Nacho" Anaya at a restaurant in Piedras Negras, a Mexican border town, specifically to serve American military wives from a nearby base. It was a makeshift snack using what was available: tortilla chips, cheese and jalapeños.

Whilst nachos were technically created in Mexico, they were invented for an American audience and became popular in the United States long before they were ever eaten in the Mexican interior. Most Mexicans view nachos as American food.

Myth 8: All Mexican Cheese Is Yellow

The reality: Mexico has a rich tradition of white, fresh cheeses that bear no resemblance to the orange, processed cheese often associated with "Mexican food." The main Mexican cheeses include:

• Queso fresco: A crumbly, mild, fresh white cheese (similar to feta)
• Queso Oaxaca: A stringy, mozzarella-like cheese used for quesadillas
• Cotija: An aged, salty, crumbly cheese (similar to Parmesan)
• Queso panela: A smooth, mild cheese that grills without melting

None of these are yellow or processed. In the UK, feta is the best substitute for queso fresco, mozzarella for Oaxaca, and Parmesan for Cotija.

Myth 9: Fajitas Are Traditional Mexican

The reality: Fajitas (grilled meat with peppers and onions, served with tortillas) are a Tex-Mex creation from the Rio Grande Valley in Texas. The word fajita refers to the cut of meat (skirt steak) rather than the dish. Fajitas became popular in Texas in the 1970s and 1980s before spreading worldwide.

In Mexico, you might find arrachera (marinated grilled skirt steak), but it is served differently, typically as tacos de arrachera rather than the sizzling platter presentation familiar to British diners.

Myth 10: Mexican Food Is Quick and Simple

The reality: Whilst some Mexican dishes are quick (tacos, quesadillas), many of the cuisine's greatest achievements are extraordinarily labour-intensive. A proper mole can take two days to prepare, involving the individual treatment of 30+ ingredients. Tamales require hours of communal preparation. Barbacoa traditionally involves digging an underground pit and slow-cooking meat overnight.

The complexity of Mexican cuisine is one reason it received UNESCO recognition. It is a cuisine built on ancient techniques, seasonal ingredients and deep cultural traditions that rival any culinary tradition in the world.

How to Experience Real Mexican Food in the UK

The UK's authentic Mexican food scene is growing rapidly. To experience the real thing:

• Seek out restaurants run by Mexican chefs (check our restaurant directory)
• Try cooking from scratch using authentic recipes (browse our recipe collection)
• Source genuine ingredients from specialist shops (see our shop listings)
• Attend Mexican food festivals, pop-ups and cooking classes
• Be open-minded and willing to try dishes you have never heard of

The gap between what most Britons think Mexican food is and what it actually is represents an enormous, delicious opportunity. There is a whole world of flavour waiting to be discovered.
