Patatas bravas are one of Spain’s most popular tapas. They’re the go-to choice for an appetizer or a snack to share along with a round of cañas. The potatoes are cut into bite-size chunks and deep fried in olive oil. The main thing that sets them apart from other varieties of what Americans know as “fries” is the shape. The sauce is usually drizzled directly onto the potatoes before serving. Bravas sauce is bright red and slightly spicy.
