In Spain, preserving the rituals of Lent – historically a period of 40 days of prayer, penance and pious abstinence from eating meat that leads up to Easter – was up until the second half of the 20th century mostly the responsibility of priests. Nowadays, however, it is more often the country’s chefs who are shaping the observance of Lent, by both maintaining and updating its delicious culinary traditions, which are still very much a part of Spain’s contemporary food culture. Each country where Lent was customarily practiced has its own special dishes in which meat is replaced with other protein-rich ingredients in order to fill the stomach. In Spain, the “king” of Lenten cuisine is cod (bacalao), introduced in the 16th century by Basque fishermen who had begun to catch it off the faraway coast of Newfoundland.

Salt cod has been a staple on the Iberian Peninsula for centuries, but in the last few decades overfishing and changes in eating habits have resulted in a significant drop in bacallà consumption. Only recently has the fish begun returning in greater numbers to our tables, and it has also become the focal point for an annual gastronomic celebration: La Ruta del Bacallà. There’s a popular saying on the Iberian Peninsula that there is one cod recipe for every day of the year, but in truth, the number is upwards of 500. In Spain, there are hundreds of cod recipes dating from the Middle Ages, with a multitude of regional variations. The most notable and sophisticated ones come from Basque country and Catalonia.

When Julián Fernández and Carmen Erdocia moved to Barcelona in 1996, they bought an old fútbol salon in the Eixample that was named Táctica, or “tactics,” in a reference to Spanish football. Julián and Carmen began serving pintxos such as tortilla de bacalao (Spanish omelet with codfish) to hungry futboleros. Eventually, the venue became so popular that they decided to convert Táctica into a Basque restaurant specializing in pintxos. The name was easy: Taktika Berri means “new tactics” in Basque.

At first glance, Restaurant Roma doesn’t appear to be anything out of the ordinary. The nondescript brown tiles covering the floors, the dark wood bar, the vaguely Mediterranean-inspired wall décor and the rectangular paper Ikea lamps are similar to those at hundreds of other midrange restaurants throughout Barcelona. Situated on a quiet street in residential Sant Gervasi, Roma isn’t somewhere you’d be likely to come across accidentally, nor is it the kind of place you’d happen to hear about, unless you (or your aunt, or coworker or a friend of a friend) lived nearby. And that would be a shame because the food at Roma is good – ridiculously delicious, in fact.

Dear Culinary Backstreets, In just about every restaurant or bar I’ve been to in Barcelona, I’ve seen a dish called “tortilla.” What exactly is a tortilla and can you recommend any places where they are done especially well? Although it would seem that much of the world imagines the inhabitants of Spain subsisting largely on paella, the truth of the matter is that it is the tortilla española, also known as tortilla de patatas (truita de patata in Catalan), that  really holds the place of honor in the hearts and stomachs of Spaniards. Often translated into English on menus as “potato omelet,” this hearty round cake of potatoes, eggs, olive oil and salt has nothing to do with the traditional French omelet, nor does it have anything in common with a Mexican tortilla. At its most basic, the Spanish tortilla is made by frying up a thick mass of sliced potatoes and eggs in olive oil and then slicing it into savory wedges.
