Editor’s note: This post wraps up “Spring (Food) Break 2013,” our weeklong look at the favorite foods of the spring season in each city Culinary Backstreets covers. 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.

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.

Once a mostly beer-free country, Spain – traditionally a land of wine drinkers – has recently started to develop a taste for the sudsy beverage, and Catalonians seem to have been the main pioneers behind this growing trend. The number of local craft breweries is increasing and so is the number of beer fans, who are also learning how to brew the drink at home. Put it all together and you have a young and adventurous market that is ready to experiment with tastes and textures to create stellar new beers with a distinct Mediterranean flavor.

Dear Culinary Backstreets, I’m traveling to Barcelona and I love visiting food markets. I’ve heard a lot about La Boquería, but are there any other markets that might be worth visiting?

Editor's Note: Sadly, this spot is now closed. Mercè Vins is exactly between two worlds, located on the quiet, narrow and dark Carrer d’Amargós, close to the shopping area of Portal de l’Àngel, near the Cathedral and Plaça de Sant Jaume, and on the border between the Barrio Gótico and Born neighborhoods, where there are numerous offices and public institutions, filled with employees looking for a breakfast that goes beyond a sad, ersatz “croissant” or for a lunch that approximates the kind of meal they would get if they were able to sneak back home.

De toda la vida is a Spanish expression that basically means “It’s been around forever,” and it’s a sure thing that the locals in Barcelona’s Gràcia neighborhood will utter those words if you ask them about Bodega Quimet. Opened in the 1950s by the Quimet family, the bodega (not to be confused with Quimet i Quimet, a popular Barcelona tapas bar) was passed down from father to son until 2010, when the younger (but nonetheless old) Quimet retired and brothers Carlos and David Montero bought the venue. David Montero had always worked as a cook and dreamed of owning his own place. However, after buying Quimet, instead of doing the renovations so typical of Barcelona bars that change hands (such as modernizing the furnishings or installing a huge flat-screen TV for showing fútbol matches), the Montero brothers made the somewhat unusual decision to keep everything, from the low prices to the décor, pretty much the same as it always had been.

At Culinary Backstreets, we are all about seeking out backstreets eating at venues serving authentic cuisine and frequented mainly by locals – an approach that usually leads both to delicious food and to prices that won’t break the bank. But how about underground dining, where even locals themselves aren’t always in on the secret?

When Xisca Ferragut left Mallorca (the largest of the Balearic Islands, located in the Mediterranean Sea off the eastern coast of Spain) and moved to Barcelona, she had no intention of opening a restaurant. Having lost her job back in Mallorca, she had decided to study sign language and become an interpreter. Then her boyfriend, Dionis Ballester, showed up and as the two struggled to find work, they noticed something: there were literally NO Mallorcan restaurants in Barcelona.

As the legend goes, a 19th-century Catalan farmer was out experimenting in his fields when he came up with a new kind of longer, juicier green onion, the calçot. In creating the onion, the farmer produced much more than a new vegetable; he also paved the way for the rise of an idiosyncratic, and distinctly Catalan, cultural event.

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.

Spain has not traditionally been known as a country of great bread, although there are some exceptional old tahonas (bakeries) scattered around here and there. But after long decades of eating poor-quality breads, typically white or light bread with excessive additives, Spaniards are finally developing their taste for the staple. In fact, the culture of bread in Spain is in full fermentation right now.

Editor's Note: Sadly, this spot is now closed. Everyone knows that Germany and France can both make a mean loaf of bread. But what about Spain? When was the last time you heard someone say something like, “What this meal really needs is some delicious Spanish bread!” You’ve never heard anyone say that and the reason is that the bread in Spain is, with few exceptions, decidedly mediocre, with even the smallest bakeries producing the majority of their “fresh-baked” product using partially baked or frozen dough made in factories using industrial yeasts and preservatives.

A hidden culinary sanctuary, El Passadís del Pep may be located in one of the most visited quarters of Barcelona, but it’s out of sight of anyone who isn’t looking for it. Once you go down the long corridor that leads to the restaurant, you don’t need to do anything, and that includes choosing what to eat. From the moment you sit down, the “house” offers you your first bottle of cava, and the celebration of food and life begins. There is no menu and there are no “daily specials,” just whatever Joan Manubens and his team decide to cook that day. The restaurant, whose name means “Pep’s Corridor,” specializes in cocina de mercado, or market cuisine, prepared in a simple, traditional Mediterranean style. As if in a ballet, the show begins when the waiters start to dance around you and the food arrives at the table in a continuous flow of abundance: Iberian cured ham, anchovies, typical Catalan bread rubbed with tomato; sautéed baby squid with rice and garlic; choice shellfish such as cañaíllas (a kind of sea snail) prepared in such a delicate way that all the natural flavor is retained; velvet crabs or spider crabs cooked without any ingredient that could detract from their natural essence.

Editor’s note: This is the penultimate installment of “Best Bites of 2012,” a roundup of our top culinary experiences over the last year. Stay tuned for our final “Best Bites” dispatch, from Istanbul, tomorrow. Restaurant Roma We hadn’t planned on bringing in La Nochevieja at Restaurant Roma, but it was nearby and we didn’t feel up for public-transport adventures on New Year’s Eve. Situated on a quiet street in the upscale but untouristy Barcelona neighborhood of Sant Gervasi, Roma is thoroughly nondescript – a neighborhood joint frequented by neighborhood people of a certain age. The wood-paneled walls, racks of Maxim magazines and TV mounted in the corner kept our expectations pretty low.

Dear Culinary Backstreets, I’ll be in Spain during the December holidays and I’m wondering if Barcelonans eat any special meal on Christmas? If so, what is it and where in the city could I try it?
