Asparagus: The Food of Kings

Louis XIV, no stranger to fine things, was so taken with asparagus that he dubbed it the king of all vegetables and commissioned special greenhouses to be built so that it could be cultivated throughout the year. While not as rigidly seasonal (or indeed quintessentially Catalan) as the calçot, fresh Spanish asparagus is available for only about three months from mid-March onward, and its increasing popularity has boosted imports. The world’s largest producers of asparagus are China, Peru and Mexico and Spain buys huge quantities to satisfy demand during autumn and winter.

While the imported varieties are perfectly good substitutes, so many air miles inevitably take their toll, as much on the environment as the product itself. Fresh, locally produced asparagus may be a little harder to come by, but a search through the markets in the next few weeks is worth the trouble for those who want to make the most of the season.

Cultivation in Spain

Cultivation is shared between a number of regions and is determined largely by the soil type, as the plant grows best in loose, sandy soils with good drainage. The highest production is found in Andalusia, followed by Castilla La Mancha, Extremadura, Aragon and Catalunya. Navarra is also famous for its asparagus and was awarded the Denominación de Origen for the white variety, the tops of which are covered and kept out of sunlight, which prevents the development of chlorophyll. Harvests are done from March into early June, although the exact start of the season is anyone’s guess. As consumers, we can reasonably assume that it begins when the first bunches (or manats) appear in the markets, although Eduard Soley, who owns a stall in the Boqueria and knows more than most about asparagus, is adamant that the season gets underway on St Joseph’s Day (March 19th) and not before.

Catalunya has a long history of growing asparagus, although production has fallen dramatically in recent years as the quality and availability of imported varieties has increased. One of the largest Catalan producers, which still distributes from Mataró, uprooted its operation some years ago and moved to Peru, where it grows larger amounts and saves on labor costs, although it still exports to Catalunya.

Local Fairs and Festivals

One example of local celebration of the vegetable is the Fira de l'Oli i l'Espàrrec (Olive Oil and Asparagus Fair). Held every year in the second weekend of March in Godall in Montsià, the southernmost comarca (county) of Catalunya. A prize is awarded to the best local asparagus producer, and visitors have a chance to sample the local olive oil and see a selection of photos charting the history of agriculture in the area.

In early April you can head to El Port de la Selva in the Alt Empordà comarca, which is the northernmost comarca on the Catalan coast, for the Fira de l'Espàrrec. This is the only artisanal fair dedicated to the espàrrec silvestre (wild asparagus), and there you can find gastronomic activities for the whole family, local foodstuffs, crafts and more.

Closer to Barcelona, the annual Fira d'Espàrrecs (Asparagus Fair) in Gavà—just a short train ride down the coast—is held in late April or early May, and welcomes over 200,000 visitors annually. First held in 1932, it was interrupted by the Civil War and post-war troubles, but the fair resumed at the beginning of the 1960s and continues to his day. While the asparagus still takes center stage, the fair has also become a showcase for a variety of local agricultural products and businesses, and is an important event in the cultural calendar of the town.

A Diuretic and Aphrodisiac?

The plant is native to the Mediterranean, and the consumption of asparagus can be traced back to the ancient Egyptians. It was also popular with the Greeks and Romans, and is included in the collection of recipes entitled De Re Coquinaria (On the Subject of Cooking) written in the fourth century and considered the oldest surviving work of its type. The asparagus was valued for its medicinal uses as much as its flavor—its diuretic properties, due largely to the high potassium content, are well known, and it was often recommended for purifying the blood. Less purifying were its effects on the soul, however, since the asparagus was also famed during the Renaissance period for its powerful influence on the libido, and was widely used as an aphrodisiac. While this undoubtedly increased its popularity with some, the Catholic Church took a sterner view and the vegetable was reportedly banned from the dining halls of numerous convents.

In Spain, the cultivation of green asparagus was probably introduced by the Romans, although the Middle Ages saw a general decline in the production of fresh vegetables. Its renewed popularity throughout Europe can in part be ascribed to the passion of Louis XIV and the inevitable rise in consumption in fashionable society. Asparagus continued to be something of a luxury item until recent times. It remains more expensive than some vegetables, but this is due to the care required during harvesting and transportation.

Originally, the asparagus consumed in Spain was the wild variety, or espárrago triguero, the name of which is taken from the Spanish word for wheat (trigo) as the tips appeared among cereal crops and even bear some resemblance. Thinner than the cultivated variety and with a slightly more pronounced flavor, the triguero still grows wild in many parts of Spain, including Catalunya, where it is sometimes referred to as the espàrrec silvestre, as it is commonly found in woodland areas. This wild asparagus is available during the early part of the year when it is warmed by the winter sun, although there are inevitably farmed varieties that prolong the season (it isn’t uncommon to find trigueros in restaurants throughout the summer, when you can be fairly certain that they won’t be wild, whatever the menu says).

The larger, farmed asparagus was popularized in Spain in the 18th century, and cultivation spread in the early part of the 20th century. It has since become indispensable in the Spanish diet, due partly to its enormous versatility and also to the properties that were prized centuries ago. Approximately 85 percent of asparagus is water and it contains very few calories and large amounts of fiber. It also contains vitamins A and C, beneficial minerals such as phosphorus, calcium and magnesium, and is an excellent antioxidant. Asparagus provides the highest amount of folic acid of any vegetable, which is important in the formation of blood cells and growth.

How to Select Good Asparagus

A good asparagus is essentially a fresh one, and this should always be easy to tell from the tips, which should be firm to the touch. At the beginning and end of the season, the stalks tend to be dryer and woodier, and it is usually necessary to discard a little more. Given their valuable vitamin and mineral content, it is best to cook asparagus as little as possible, which also helps to preserve their subtle flavor, but a glance at menus around Barcelona will give you an idea of their versatility, as you will almost certainly see them in risottos, revueltos, tortillas, soups, grilled as a starter or with a main dish, or even served as a purée to accompany meat or seafood.

Probably the healthiest method is to steam them, although perhaps the most typical way to eat asparagus in Catalunya is simply grilled and served with a romesco sauce. For the more adventurous (and well-heeled), there is always asparagus foam, although the mention of it was met with looks of disapproval by a number of stall-holders in a local market.

Eat it fresh, keep it simple and rejoice that once again it’s the season for the king of vegetables.
