Padrón pepper is a Galician pepper originating from the Padrón municipality. The peppers range in color from bright green to yellowish green. Although they are usually mild in flavor, about one in ten of these peppers is spicy as hell, but it's almost impossible to tell them apart until you taste them, which is like playing Russian roulette with peppers.
Padrón peppers are traditionally fried in olive oil and seasoned with coarse sea salt. They are served in most tapa bars and restaurants in the region, and it's recommended to have a glass of beer, wine, or cider nearby - in case you eat a few of the spicy ones.
