Birria tacos are traditionally made with goat meat, but can also use chicken or beef. The tacos are then dipped in consomé, a type of stew made with beef stock, onions, garlic, and more.
While the dish originates in Mexico, it has also become popular in cities like Los Angeles and New York City, where the Birria-Landia taco truck often has lines down the street, the New York Times reported.
