Have you tried Padrón Peppers?
Some are hot, some are not
Have you ever heard of Padrón peppers? They're quite a common dish here in Spain, they're served as a tapa on a big plate to share. Fried in olive oil, leaving the stem so you can use your hands to eat them, and sprinkled with coarse salt, these peppers are a delicacy.
But their distinctive flavour is not what made them famous. They grow in the municipality of Padrón, Galicia, northwestern Spain, and, depending on the weather conditions, while most of them have a mild, sweet flavour, 10-25% of them can be quite hot.
As they say in Galician language: "Os pementos de Padrón: uns pican e outros non." This translates to, "Padron peppers, some are hot, some are not".
Since it's nearly impossible to differentiate on the plate which one is hot, sharing this dish and waiting to see who gets the hot one is a fun part of the experience, like playing a game of pepper Russian roulette.
