A pupusa (, from Pipil pupusaw) is a traditional Salvadoran dish made of a thick, handmade corn tortilla (made using masa de maíz, a cornmeal dough used in Mesoamerican cuisine) that is usually filled with a blend of the following:

• cheese (queso, usually a soft cheese called quesillo found throughout Central America)
• cooked and seasoned pork meat ground to a paste consistency (called chicharrón, not to be confused with fried pork rind, which is also known as chicharrón in some other countries)
• refried beans (frijoles refritos), or queso con loroco (loroco is a vine flower bud from Central America).
