At the Everett Family Farm's farmers market booth, a sign read "el famoso Padrón.” The wrinkled appearance of these small Galician peppers reminded me of pepperoncini.
Galicia is an autonomous region of Spain which is bordered on the south by Portugal and on the north and west by the Atlantic Ocean. Its economy is driven by fishing, manufacturing and agriculture. From one of its municipalities come these pementos de Padrón, only relatively recently available stateside.
Generally a sweet pepper, but occasionally one with an overabundance of capsaicin sneaks in amongst its mellow brethren, earning these capsicums the nickname Russian Roulette. A Galician saying warns, "Peppers of Padrón, some of them hot, and others not." Apparently, if left to mature to a deep red, they are quite spicy.
