Cecina is a thinly sliced and salted beef or pork meat that is popular in Mexico City. The meat is typically marinated in a mixture of salt, garlic, and spices, and then air-dried or smoked. Cecina has a rich and savory flavor and a slightly chewy texture. It is often served in tacos, quesadillas, or as a topping for tostadas. The meat can also be enjoyed on its own as a snack.
