Frito Pie

Two competing origin stories: New Mexico claims it via Teresa Hernández at the Woolworth's lunch counter in Santa Fe (1960s), where she ladled her mother's homemade red chili into open Fritos bags. The in-bag «walking taco» form only took off after 1962, when the company switched from paper to grease-proof cellophane bags (food historian Robb Walsh). Texas counters that Daisy Doolin, mother of Fritos founder Charles Elmer Doolin, was making «Fritos chili pie» at home in San Antonio in the 1930s — Frito-Lay's PR department served «Fritos chili pie» to the Dallas Dietetic Association in 1949. Kaleta Doolin's 2011 family history argues both family-origin legends are myths — the dish was actually devised by the company's marketing team. Both states claim it; New Mexico's Santa Fe Five & Dime is now closed but the recipe stays.

Two-state argument: New Mexico credits Teresa Hernández at the Santa Fe Woolworth's lunch counter (1960s); Texas counters with Daisy Doolin (mother of Fritos founder Charles Elmer) making it at home in 1930s San Antonio.

First bite from the top is dry crunch, hot meat, cool cheese melting through it, the snap of raw onion, vinegar bite of jalapeño, then sour cream. By the third spoonful you're hitting the chili-soaked Fritos at the bottom — softened but still corn-sweet, the texture of well-stewed corn dumplings. Eaten standing at a fair, the bag warm in your hand. Benchmark: the bag should warp from the heat but not split.

Fritos are not regular tortilla chips — they're made from masa extruded through a die and deep-fried in corn oil, so they hold structure under hot liquid for far longer than a thinner chip. They soften but don't disintegrate, which is why no other corn chip works as a substitute. The chili needs masa harina (1 tbsp per 500g meat) as binder — without it, the liquid soaks through too fast and the bottom chips dissolve to mush in 90 seconds.
