The pupusa is a a thick, stuffed tortilla, and a staple of El Salvador's national cuisine. It is usually stuffed with cheese, refried beans, or other fillings such as beef or pork rind, and then fried. Though pupusas are identified as Salvadoran in the US, they are also traditional in Honduras and Guatemala.
Migration
Though there is archaeological evidence that pupusas have been made in El Salvador for thousand's of years, the 20th century history of the dish is one of constant migration. First, in the 1950s and 1960s, rural Salvadorans with native roots moved to the cities and took their traditional food with them, establishing the pupusa as a national dish. Later, during the Salvadoran Civil War of the 1980s, there was a steady migration northward, establishing Salvadoran communities in every major US and Canadian city. The result has been an increasingly popular addition to North American cuisine.
