Bringing the aroma of the vertical spit home: the story of tacos al pastor
In the early-evening kitchen, dried chiles sink into hot water and release a smell that is less spicy than it is like dried fruit and an old wooden crate. Blend them with achiote, vinegar, garlic and pineapple, and the red color moves into the pork. The moment it hits the skillet, sweet-sour steam and the smell of sizzling fat rise, and suddenly the table feels a lot closer to a taco stand.
Tacos al pastor are Mexican tacos made from adobo-marinated pork roasted on a vertical rotating spit called a trompo, shaved off in thin slices and piled onto corn tortillas. The name al pastor translates as "shepherd style," but today's taco stands use mostly pork. The dish is often explained as the meeting of the vertical-spit meat tradition brought by Lebanese immigrants with Mexican chiles, achiote and tortillas.
The biggest question at home is the missing trompo. Stacking a large mass of meat on a vertical spit and shaving off the outside can't be reproduced as is in a home kitchen. So this recipe marinates thinly sliced pork shoulder in the red marinade, sears it over fairly high heat, then chops it and sears it again with pineapple. It is not a perfect copy of the trompo; it is a way to keep the "red aroma, char, acidity and sweet juice" in an ordinary kitchen.
Among Mexico's tacos and their relatives, basic tacos are a quick build of grilled beef, chunky salsa and warm tortillas, birria de res is a red beef stew with consomé, tinga de pollo is chicken simmered with chipotle, and pozole rojo (in Japanese) is a big pot of hominy soup. If you lean toward breakfast or brunch, chilaquiles, fried tortillas briefly simmered in salsa, are a very Mexican way to use up leftover tortillas. Al pastor has more of the street stand's lightness than any of them: you cook it and eat it right away. Stack two small tortillas and top them with meat, pineapple, white onion, cilantro and lime, and every bite switches between fat and acidity.
In Spanish it is written tacos al pastor. In Japanese the spelling varies. In this article, "tacos al pastor" refers to the dish and "al pastor" to the meat filling.
What to keep without a trompo: red marinade, char and juice
Gathering the ingredients alone won't make tacos al pastor taste right. What matters is not simply stir-frying the meat but searing it in a thin layer over fairly high heat, then chopping it finely at the end to build up more char. The pineapple isn't only there to sweeten the meat; it also cuts through the fat as you eat.
| Element at the stand | Its role at the stand | Home version | Watch out for |
|---|---|---|---|
| Trompo | Meat stacked vertically, outside shaved off | Spread thin slices to sear, then chop and sear again | Stir-frying thick meat all at once turns it into a braise |
| Adobo | Chiles, achiote and vinegar create the red aroma | Blend or pound into a smooth paste in a blender or mortar | A coarse paste scorches easily and stays gritty |
| Pineapple | Roasts on top of the meat and adds sweet-sour notes | Use some in the marinade and some for finishing | Too much makes the meat overly soft |
| Corn tortillas | Hold the fat and acidity of the meat | Small store-bought corn tortillas | They crack easily when cold |
| White onion and cilantro | Fresh, raw aromas that lighten the fat | Onion, cilantro, scallions | Using only scallions shifts the flavor toward East Asia |
A broiler or the top element of an oven adds more char, but a skillet makes the heat easier to judge the first time. Spread the meat out to sear, don't stir too much, and only use high heat for the final sear. Keeping just these three rules gives you a home-style taco that is plenty of fun.
Ingredients (serves 4)
This makes about 12 small tacos, or a main course for 4. Rather than ultra-thin slices meant for hot pot, use 3–4 mm slices for grilling, or partially freeze a piece of pork shoulder and slice it thinly yourself; that gives you both char and a meaty bite.
This dish involves pork, corn and, depending on the product, tortillas that contain wheat. Pineapple and garlic can irritate some people's mouths. Don't use marinade that has touched raw meat as a sauce as it is, and wash utensils with detergent before handling the garnishes or tortillas.
Achiote is what creates the red color and a light earthiness. It can be hard to find in regular supermarkets, so if you plan to make al pastor more than once, it is the first thing worth tracking down; Latin American grocers and online spice shops usually carry the paste or the seeds (annatto). Paprika alone can make the meat red, but achiote brings out the orange hue typical of Mexican cooking.
Even a small amount of oregano ties together the sharp edges of the chiles and vinegar. If the jar at home is old and has lost its aroma, the whole thing tends to end up merely red and spicy, so if you cook Mexican food often, a fresh jar is worth it.
A mortar and pestle is not essential. Still, it helps to even out the aroma when you use annatto seeds, or when you want to grind garlic, oregano and cumin with a little vinegar. It lets small amounts of spice do their work better than a blender alone.
Because the pork is thin, it dries out quickly if overcooked. Especially when serving children or older family members, checking with a thermometer that the center of a thicker piece is hot gives peace of mind. A meat thermometer is a useful tool so you don't judge by color alone.
Method
The work splits into the first half, making the marinade, and the second half, quick searing. Once the pork is marinating, prepare the garnishes and tortillas before you start searing so you can bring everything to the table while it is hot.
After chopping the skillet-seared meat, you can also spread it on a foil-lined tray and broil it on medium for 3–4 minutes. Take it out when the surface is dry and lightly charred, then combine with the pineapple. You get more char, but it dries out fast if left alone, so finishing in the skillet is more reliable the first time.
Substitutes and what goes wrong
Al pastor is not a fiery dish. The red color looks spicy, but at its core are the fruitiness of dried chiles, the color of achiote, the acidity of vinegar and pineapple, and the fat of seared pork. If you only add heat, it drifts away from a street taco toward a painfully hot chile stir-fry.
| Ingredient or issue | Role in Mexico | Substitute | Watch out for |
|---|---|---|---|
| Achiote | Red-orange color, light earthiness | Annatto seeds, a little paprika | Paprika helps the color; the aroma is different |
| Guajillo | Red color, fruitiness, slight astringency | Paprika with a little ground red chile | Using only ground chile puts heat first |
| Ancho | Sweetness like dried fruit | 2 tsp raisins | Too much makes the sauce sweet |
| Pineapple | Acidity, sweetness, slightly tenderizes the meat | Canned pineapple, a little orange juice | Long marinating makes the meat fall apart |
| Pork shoulder | Balance of fat and meatiness | Mix in a little pork belly or pork leg | Leg alone dries out easily |
| Corn tortillas | Aroma and a base for the filling | Flour tortillas | Delicious over rice as a different dish, but the taco character changes |
| Problem | Why it happens | How to fix it |
|---|---|---|
| Bitter | The dried chiles burned, or the adobo is coarse | Don't use burnt chiles. For slight bitterness, serve with extra pineapple and lime |
| Watery | Too much meat in the pan, or wet pineapple | Take the meat out, dry the pan over high heat, then sear again |
| Tough meat | Meat that was too thin was cooked too long, or left on high heat | Use 3–4 mm slices and keep the second sear short |
| Too sweet | Too much pineapple juice and canned pineapple | Add acidity with lime, onion and salsa. Halve the juice next time |
| Tacos crack | Tortillas are cold or dry | Warm them over medium heat and keep them wrapped in a cloth |
Pineapple tenderizes meat. That's useful, but marinating too long makes the surface break down and release more water when seared. This recipe uses 2 hours as the standard and has you sear the meat within 8 hours at most.
Storage and serving
Put only the cooked al pastor meat into a clean storage container, let it cool slightly, and keep it refrigerated for about 2 days. To freeze, flatten it in single-serving portions and use within 2–3 weeks. Don't store the garnishes with it; keep the onion, cilantro, pineapple and tortillas separate. If everything goes in together, by the next day the tortillas are soggy and the cilantro smells heavy.
To reheat, a skillet works better than finishing in the microwave alone. For refrigerated meat, heat the skillet over medium for 1 minute, add the meat and cook 2–3 minutes until it is hot throughout and the edges dry out a little. If frozen, thaw it in the fridge and reheat the same way over medium heat. Only if it seems dry, add 1 tsp of water, then cook off the moisture over high heat for about 20 seconds at the end.
At the table, setting out several small bowls feels more like al pastor than serving only a platter of meat. Putting out white onion, cilantro, lime and salsa separately lets people who don't like heat build their own bites. Don't bring out all the tortillas at once; rewarming them 6 at a time keeps them from cracking later in the meal and better able to hold the fat.
| Occasion | How to serve | Dishes to pair |
|---|---|---|
| Weeknight dinner | Meat on a platter, garnishes in small bowls, tortillas wrapped in a cloth | Start with a little pozole rojo (in Japanese) for a more filling meal |
| Weekend lunch | Set out 2 kinds of salsa and let everyone roll their own small tacos | Serve alongside tinga de pollo to taste the difference between chicken and pork |
| Next-day lunch box | Meat, a fried egg and seared pineapple over rice | Pack the lime separately and squeeze it just before eating |
| Snacks for guests | Cut small tortillas in half and top each with a little meat | Put mole poblano (in Japanese) on a separate plate to compare a rich sauce |
When you tire of tacos, the next day can take a different form. Spoon it over warm rice with a fried egg and salsa for a quick lunch. Sandwich it with cheese in flour tortillas and it becomes quesadilla-style. Set it next to the red stew birria de res and you can see the difference between "stewed" and "seared" within the same taco family. For a larger spread, serve a small bowl of pozole rojo (in Japanese) first and then sear the al pastor as the main course, for a flow that feels like a Mexican table.
FAQ
Can I make it without achiote?
Yes, but the color and aroma change. 1 tbsp paprika, a little ground red chile and 2 tsp raisins add redness and sweetness, but you won't get achiote's distinctive orange or its light earthiness. Try the substitutes first, and if you like the dish, get achiote or annatto seeds next time.
Can I use canned pineapple?
Yes. The juice is easy to use in the marinade, and the fruit can go into the finish. But pineapple in syrup is quite sweet, so start with 50 ml of juice instead of 80 ml. Pat the fruit well dry and hit it with high heat during the second sear so the sweetness doesn't get heavy.
Can I use only pork belly?
You can, but it will be fatty. If you use only belly, transfer the seared meat to paper towels to blot off some fat before chopping and searing again. The easiest mix to eat at home is 500 g shoulder with 200 g belly.
Can I make it mild for children?
Yes. Don't use hot chiles such as chile de árbol; stick mainly to guajillo and ancho, or paprika. Serve the salsa on the side, and use less lime and onion for the children's portions. Garlic and acidity define the dish, though, so halving them works better than leaving them out.
What if I can't get tortillas?
Flour tortillas are the closest. Next best are thin pitas or small flatbreads. It is also good over rice or on sandwich bread, but then think of it as al pastor-style meat rather than tacos.
Can I make it in the oven?
Yes. Set a rack on a baking sheet, spread the marinated meat without overlapping, and roast at 230°C (450°F) for 8 minutes. Flip and roast another 5–7 minutes; when the edges char, take it out, chop it, and sear it again with the pineapple in a skillet for 2 minutes. Finishing in the skillet to drive off moisture makes it easier to put in tacos than using the oven alone.
At home, char instead of shave
When making tacos al pastor at home, you don't need to force a substitute for the trompo. What to protect is the red marinade of dried chiles and achiote, thinly sliced pork, short bursts of high heat, pineapple and warm tortillas. Since you can't shave the meat as a stand does, sear it, chop it and char it again instead. In that order, even a skillet gives off the cheerful aroma of al pastor.
If you're unsure what to shop for, start with pork shoulder, corn tortillas, pineapple and achiote. You can make it without every dried chile, but even one kind changes the aroma. Once the meat is done, pile on onion, cilantro and lime while it is hot. The moment you pick up a small taco, the time you spent waiting in the kitchen pays off.
