A pupusa is a thick griddle cake or flatbread made with cornmeal or rice flour, similar to the Colombian and Venezuelan arepa. In El Salvador, pupusas have been declared the national dish and have a specific day to celebrate it. They are usually stuffed with one or more ingredients, which may include cheese (such as quesillo or cheese with loroco buds), chicharrn, squash, or refried beans. Pupusas are typically accompanied by curtido (a spicy fermented cabbage slaw or relish) and tomato salsa, and are traditionally eaten by hand.
Pupusas are a popular street food in El Salvador and are also commonly served in restaurants. They are a relatively inexpensive and filling meal, and are a good source of carbohydrates and protein. Pupusas can be made ahead of time and reheated when ready to eat, making them a convenient option for busy families.
