What are Padrón peppers?
Padrón peppers are typically small in size, with a length ranging between 3 to 7 cm (1 to 3 inches). They have a slightly elongated canonical shape, making them quite recognizable. As a member of the Capsicum annuum, L. cultivar, they are bright green in colour with a relatively thin skin.
They have a unique sweet and mild flavour profile, but one of their most notable characteristics is that a small percentage are unexpectedly hot. There is a popular saying in Spain ‘unos pican y otros no‘ meaning ‘some are hot and some not’, referring to the occasional Padrón pepper that is very spicy. As you cannot see which ones are hot and which ones not, the only way to know is to give it a taste. Eating these peppers is playing Spanish Roulette, you never know who will eat the spicy one.
Brief history
The cultivation of peppers in Spain began in the 15th century when seeds were brought by Columbus from the New World. However, the cultivation of Padrón peppers is specifically connected to pepper seeds from Tabasco, Mexico, which were brought to Spain during the 17th century by Franciscan monks to the Convento de San Antonio in Herbón, in the Padrón municipality. In Galicia, these peppers are often called Pimientos de Herbón, for obvious reasons.
The Franciscan monks played a crucial role in the initial cultivation and selective breeding of Padrón peppers, developing cultivation techniques that enhanced their unique characteristics. They shared their knowledge with the local communities and only in very restricted areas; the parish of Herbón and the valleys surrounding the Sar and Ulla rivers bordered by the Barbanza Peninsula and mountain ranges.
Over the years, the sales of dried and ground peppers became an important source of income for the Padrón region. At that time the peppers were harvested mature and red in colour. The current Padrón peppers are harvested early, hence their green colour.
Denomination of origin
The Pimiento de Padrón variety cultivated in its place of origin is a Denominación de Origen Protegida (DOP), or Galician Protected Designation of Origin (PDO). While this type of pepper is now grown in various parts of the world, only those from Galicia, known as Pimiento de Herbón, have the unique characteristics, taste, and level of spiciness that define its high quality. Peppers with PDO status are considered the most authentic and flavourful.
Why are some spicy and others not?
The level of spiciness in Padrón peppers depends on the amount of capsaicinoids they contain. Originating from a spicy variety, farmers have spent centuries selectively breeding and cultivating these peppers to minimize their spiciness and optimize their size, shape, and taste. Seeds were meticulously passed down and cultivated only in specific areas with specialized production systems to ensure high-quality peppers with unique characteristics.
Despite these efforts to enhance sweetness, occasionally, a spicy pepper still emerges, as sometimes a plant responds to a stressful environmental situation causing it to produce capsaicin. Approximately 1 out of 10 Padrón peppers are very hot, ranging between 500 and 2,500 Scoville Heat Units (SHU). Most are mild, but a very small percentage can still be unexpectedly spicy.
The amount of spiciness also heavily depends on the type of soil, the area, temperature and other environmental conditions.
How to cook Padrón peppers
Although Padrón peppers are produced in various parts of the world, the authentic Herbón peppers are seasonal and only harvested between May and October. They are at their best during the summer months.
Traditionally, pimientos de Padrón are served as Spanish tapas and are prepared by either grilling or frying them in olive oil. Slow cook the peppers in olive oil until the skin blisters but does not burnt and just add a generous amount of coarse sea salt or Kosher salt. Serve with slices of bread or boiled potatoes. Here is the recipe for blistered Padrón peppers.
Other culinary uses of these peppers include pickling, stuffing, sautéing or grilling in the oven, like these feta stuffed Padrón peppers. You often see them as part of a pintxo (tapas from the Basque Country), or in a salad. Their bright green color adds vibrance to a dish and their distinct taste provides a unique aroma.
As a substitute, if Padrón peppers are not available, you could use Shishito peppers which have a similar appearance and mild taste.
Cultural significance – Festivals and traditions
Padrón peppers have become an integral part of Galician cuisine and culture. They are celebrated in local festivals highlighting their importance to the region.
Every first Sunday of August, already since 1978, the village of Herbón celebrates the Padrón pepper with its own festival. Known as La Festa do Pemento de Herbón (Fiesta del Pimiento de Herbón), this festival honours the famous Herbón peppers, which are widely more known as Padrón peppers and which have been cultivated by local farmers in the area for centuries. These peppers hold a special place in the culinary traditions of Galicia, and the festival aims to promote their unique flavour and appeal. The festival has become well known and attracts visitors from all over.
The day features a variety of activities, including a mass to inaugurate the festival, a floral offering to the Permenteira, various awards, and of course, the tasting and sampling of these delicious peppers. It’s a celebration not only of the Herbón pepper but also of other local gastronomic and artisanal products, like cheeses, sausages, wines and liquors.
