Pupusas are a traditional dish from El Salvador, made of thick corn tortillas filled with various ingredients. Common fillings include cheese, beans, and pork, but they can also contain vegetables or other meats. Pupusas are typically served with a side of curtido, a pickled cabbage slaw, and salsa roja, a tomato-based sauce. These delicious treats are often enjoyed as street food and are popular in both homes and restaurants. The preparation involves mixing masa (corn dough) with the desired filling, shaping it into a disc, and cooking it on a griddle until golden brown. Pupusas are a staple of Salvadoran cuisine and are celebrated for their flavor and versatility.
