Mexico City's direct descendant of the doner, created by Lebanese immigrants who swapped lamb shawarma for pork marinated in achiote and guajillo chilies, stacked on a vertical trompo spit and crowned with pineapple. Taqueros shave the crisp edges straight into corn tortillas, making it arguably the most famous evolution of the kebab in the Americas.
Also known as: al pastor, trompo al pastor, tacos de trompo, adobada tacos, pastor taco spit

Ingredients
- 1 kg pork shoulder, in 5 mm slices
- 4 dried guajillo chilies, seeded
- 2 tbsp achiote paste
- 60 ml white vinegar
- 100 ml pineapple juice
- 3 garlic cloves
- 1 tsp dried oregano and 1/2 tsp ground cumin
- 1.5 tsp salt
- 200 g fresh pineapple, plus a thick slab for the crown
- corn tortillas, white onion, coriander and limes, to serve
How to make it
- 1
Soak the guajillos in hot water 15 minutes, then blend with the achiote, vinegar, pineapple juice, garlic, oregano, cumin and salt into a smooth adobo.
- 2
Paint every pork slice and marinate overnight.
- 3
Build a home trompo: drive two skewers through a thick onion slice on a roasting tray and stack the pork flat into a tight tower, crowned with the pineapple slab.
- 4
Roast at 200°C for about 1 hour, until the edges char and the tower is cooked through; rest 10 minutes.
- 5
Shave thin slivers down the stack, sizzle them 30 seconds in a searing pan with diced pineapple, and pile onto double tortillas with onion, coriander and lime.
Pro tip: The post-carve sizzle on a screaming-hot pan restores the crisp trompo edge an oven cannot make — skip it and the tacos taste steamed.
The story of Tacos al Pastor
Tacos al pastor is Mexico City's direct descendant of the doner, and its lineage is documented rather than speculative. Lebanese immigrants brought the vertical spit to Mexico in the early twentieth century; over the following decades the lamb became pork, the marinade became achiote and guajillo, the pita became a corn tortilla, and a pineapple was set on top of the trompo.
It is arguably the most successful evolution of the kebab anywhere in the world, and in Mexico City it is genuinely ubiquitous — the trompo turning in a taquería doorway is one of the city's defining images. Its intermediate form, tacos árabes in Puebla, still exists and shows the transition mid-stream.
The technique that defines it
The trompo is built from thin slices of pork shoulder marinated in a chilli-and-achiote adobo and stacked tightly, with the fat distributed so it bastes downward. The pineapple crowning the top is not only decoration: its juices run down the stack, and bromelain, its protein-digesting enzyme, tenderises the outer layer as it goes.
The taquero's cut is the skill. Meat is shaved from the crisping outer edge with a long knife in a single motion, caught on the tortilla held in the other hand, and — in the classic flourish — a piece of pineapple is sliced off the top and flipped through the air onto the taco. The crisp edge is the whole point; a taco of soft interior meat is a failure.
Choosing your ingredients
Pork shoulder, sliced thin, is the correct cut — it has the fat to survive a long turn on the spit. The adobo is guajillo and ancho chillies, achiote paste, garlic, cumin, oregano, vinegar and a little pineapple juice.
For a home version, marinate the slices, stack them tightly in a loaf tin with pineapple slices between, roast, chill, then slice thin and crisp hard in a very hot pan. Corn tortillas, small, doubled. Chopped onion, coriander, lime and a salsa — usually a salsa verde or a chilli de árbol.
Mistakes that ruin it
Not crisping the meat
The crisp edge from the spit is the defining texture. Meat that has only been warmed is not al pastor.
Lean pork
Shoulder with its fat. Loin dries out and the stack does not baste itself.
Too much pineapple in the marinade
Bromelain breaks down protein aggressively. A little juice is fine; a long soak turns the pork to mush.
Large flour tortillas
Al pastor uses small corn tortillas, usually doubled. The scale is part of the dish.
How it is served
Two small corn tortillas per taco, meat, finely chopped white onion, coriander, a piece of grilled pineapple, lime and salsa. Eaten standing at the taquería, several at a time, late. Nothing else is required and nothing else is offered.
Questions about Tacos al Pastor
Is al pastor really descended from the doner?
Yes, directly. Lebanese immigrants brought the vertical spit to Mexico in the early twentieth century; tacos árabes in Puebla is the intermediate form and still exists.
Why is there pineapple on top?
Its juices run down the stack and its bromelain enzyme tenderises the outer layer. It is also sliced off and served on the taco.
Can I make al pastor without a trompo?
Yes — stack the marinated slices tightly in a loaf tin with pineapple between, roast, chill, slice thin and crisp hard in a very hot pan.
What cut of pork is used?
Shoulder, sliced thin. It has the fat needed to survive a long turn on the spit and to baste the stack.
