Tacos al Pastor is a classic Mexican dish that originated in Mexico City. It consists of thinly sliced marinated pork that is cooked on a vertical spit, similar to shawarma. The pork is typically seasoned with a combination of spices, including achiote, garlic, and various chili peppers. The meat is then sliced off the spit and served on small corn tortillas, topped with pineapple, cilantro, and onions. Tacos al Pastor are known for their delicious combination of flavors, with the tender and flavorful pork complemented by the sweetness of the pineapple and the freshness of the cilantro and onions.
