Is “pastor” the same as “al pastor”?
Usually, yes. Most menus use pastor as shorthand for tacos al pastor, which is the fuller name. Either way, you are looking at chile-marinated pork with pineapple, inspired by Lebanese shawarma techniques that became a Mexico City classic.
What cut of pork should I use?
Pork shoulder is the most forgiving and stays juicy. Pork loin works too, but it is leaner, so do not overcook it. For the quickest cook and best browning, slice it very thin (about 1/8 to 1/4 inch). Tip: pop the pork in the freezer for 15 to 20 minutes first so it firms up and slices easier.
I cannot find guajillo or ancho chiles. What can I use?
If you can find only one, use guajillo. If you cannot find either, substitute 2 to 3 tablespoons chile powder plus 1 teaspoon smoked paprika. It will not be identical, but it will still be very good.
Do I have to add achiote?
No. Achiote paste adds a classic earthy flavor and deep color, but this recipe still works without it. If you skip it, add an extra 1 teaspoon smoked paprika and a pinch more salt.
Can I make these on the grill?
Absolutely. Skewer marinated pork pieces (or use a grill basket), grill over medium-high heat until browned and cooked through, then chop and finish in a hot cast iron skillet for extra crisp if you want.
How do I keep tortillas warm for a crowd?
Wrap them in a clean kitchen towel and tuck into a low oven (200°F). Or stack them in foil with a damp paper towel inside to keep them soft.
