Padrón peppers (pementos de Padrón) are a variety of peppers from the municipality of Padrón in Galicia. They are a small pepper ranging from bright green to yellowish green, and occasionally red.
Their peculiarity lies on the fact that, while their taste is usually mild, a minority (10-25%) are particularly hot. Whether a given pepper ends up being hot or mild depends on the amount of water and sunlight it receives during its growth, in addition to temperature.
The peppers are customarily fried in oil, sprinkled with coarse salt and served as tapas.
