Wheat allergy, understood in Spanish.

Mole · mole negro / mole poblano

Traditional mole negro and mole poblano contain peanuts, sesame seeds, and almonds all ground invisibly into the sauce alongside dried chiles and chocolate — a single plate of mole can trigger reactions to multiple allergens simultaneously, and none are detectable by sight or taste. In coastal Oaxaca, mole negro may also contain dried-shrimp broth, adding a shellfish allergen.

Peanuts and sesame are confirmed load-bearing ingredients in mole negro and mole poblano (Rick Bayless, Larousse Cocina, Pati Jinich). Almonds are standard in mole poblano; walnuts and pecans also appear in mole negro. Several mole varieties (coloradito, rojo, manchamantel) are thickened with stale bread or breadcrumbs, making them unsafe for celiac travelers. The shellfish risk (dried shrimp broth) is specific to Isthmus of Tehuantepec and coastal Oaxacan variants. Ask specifically: '¿Este mole lleva cacahuate, ajonjolí, nueces, o pan?'

Flour tortillas · tortillas de harina

Flour tortillas are made from wheat flour and contain gluten; they are the default for tacos, quesadillas, burritos, and fajitas across northern Mexico, and traditional recipes also include pork lard. Many travelers wrongly assume all Mexican tortillas are corn-based and unknowingly consume gluten and pork fat without any menu warning.

Corn tortillas dominate in central and southern Mexico; wheat flour tortillas are the default in Sonora, Chihuahua, Nuevo León, Sinaloa, and Baja California. Traditional recipes use pork lard (manteca); modern or restaurant versions often substitute vegetable shortening or butter. Some recipes also use butter and warm milk, adding dairy. Some establishments press both corn and wheat tortillas on the same surface. Always ask for '100% masa/maiz' and confirm the fat source.

Tamales · tamales / masa para tamales

Traditional tamale masa (corn dough) is made with pork lard beaten directly into the dough itself, not just into the filling, so tamales contain pork even when the visible filling appears meat-free. Sweet regional varieties such as tamales canarios are made with butter and condensed milk, and tamales de harina from Michoacán are wheat-flour tamales that look identical to corn tamales.

Lard in the masa is structural and non-removable in traditional savory preparations. Sweet varieties (tamales canarios, tamales de elote) use butter and condensed milk instead of lard and are dairy-intensive. Wheat-flour tamales (tamales de harina, Michoacán origin) are sold alongside corn tamales with no visual distinction. In coastal Oaxaca and the Isthmus of Tehuantepec, tamales de camarón seco contain dried shrimp in the filling, visually indistinguishable from plain corn tamales. Ask: '¿La masa lleva manteca de cerdo?'
