If you eat only one thing in El Salvador, make it a pupusa.

No food is more typically Salvadoran: it's a fried tortilla filled with beans, cheese, and/or chicharrón (pork skin). A pupusa called a revuelta has all three fillings mixed together. Delicious pupusas de arroz are made with rice flour and are not quite as thick; rather, they have a certain lightness, though they are still quite filling. Loroco, a sprouty green local vegetable, is also a popular and interesting filling. All are found in pupuserías, where they're served with spicy tomato sauce and a vinegary pickled cabbage and carrot concoction called curtido.
