Pimientos de Padrón. Seen here in La Boqueria, Barcelona’s central market. And seen on virtually every tapas menu in Spain. Fried, salted and delivered tasty and green, they sometimes carry a surprise message. Every once in awhile, these sweet little guys give way to an errant picante one. You can tell when this happens to someone else because they grab for their water glass. And you can tell when it happens to you, well, in a more incendiary way.
