Set out a scale and the equipment for Al pastor. Heat to a hot grate, about 450°F / 232°C and give it 5 minutes so the surface is actually hot. Weigh pork tenderloin, pineapple, chipotle in adobo, yellow onion, cilantro, corn tortilla, lime, ground cumin, kosher salt, olive oil. Al pastor is cooked in Mexico City as its own plate, not as a copy of a restaurant menu. Marinate the pork with chile and pineapple, grill it through, and chop it onto warm tortillas. A vertical spit is the taqueria method. A hot pan cooks the same meat. Amounts are for 4 from foods this library can count.
