National Mexican tradition — particularly associated with Jalisco, Sonora, and Northern Mexico; also popular in Oaxaca and Puebla with regional variations
Menudo is Mexico's most celebrated restorative soup — a long-simmered broth of cleaned beef tripe (honeycomb and book tripe) with hominy, dried red chiles (ancho, guajillo, pasilla), dried oregano, and lime. Made primarily on weekends (Saturdays and Sundays), it is considered the canonical hangover cure and is eaten by families at weekend breakfast. The broth must be gelatinous from the tripe collagen and deeply red from the chile base. The tripe cooking time is 3–4 hours minimum.
Rich, deeply red, gelatinous — the tripe collagen creates a body unlike any other broth; dried chile adds earthy warmth
{"Tripe cleaning is the most critical step — vinegar + salt + repeated rinsing + par-boiling before main cook","3–4 hour minimum simmer — tripe is extremely tough and must fully tenderise","Dried chile base added after tripe is mostly tender — chiles are toasted, soaked, blended, strained, then added","Hominy added in the final 30 minutes — it is pre-cooked; just needs to heat through and absorb flavour","Garnish table: dried oregano, chopped white onion, lime, dried chile powder — all on the side"}
{"Clean tripe: scrub with coarse salt and lime juice, rinse 3 times, par-boil 20 minutes, drain, repeat once more","For depth: add a split and charred onion to the tripe cooking water","Menudo freezes perfectly — make a large batch; the collagen content makes it gel when cold","Traditional garnish in Northern Mexico includes chopped fresh onion + dried oregano only — simpler than central Mexican style"}
{"Insufficient tripe cleaning — the main source of failure; off flavours permeate the soup","Short cook time — tough tripe is the primary failure mode","Adding the dried chile base too early — it burns before the tripe cooks","Using canned hominy without draining — the canning liquid makes the broth starchy and flat"}
