Tacos al Pastor

Tacos al pastor are thin slices of pork marinated in dried chillies, achiote and spices, stacked on a vertical spit (trompo) and roasted until the edges char and crisp. The taquero shaves the meat straight onto small warm corn tortillas, topping each with a sliver of pineapple, white onion, coriander and a squeeze of lime.

Sweet, smoky, sour and savoury at once, they are the late-night soul of Mexican street eating.

Al pastor is a delicious migration story. Lebanese immigrants brought spit-grilled, shawarma-style meat to Mexico in the early 20th century; Mexican cooks adapted it from lamb to chilli-marinated pork and added the now-iconic pineapple, creating "al pastor" — "shepherd style."

Centred on Mexico City and Puebla, it became one of the country's signature street tacos. It is a vivid example of how immigrant techniques fuse with local ingredients to create something entirely new.
