You are what you eat, as the saying goes. Is it any surprise, then, that food figures so largely in popular culture all over the world? In Spain, we have a veritable cornucopia of food-related expressions. Here’s a taste: Dar una torta, “to give a cake.” To slap someone. But darse una torta, “give a cake to yourself,” means you hit something else. It’s a mild, lighthearted expression, even with tortazo, which is a bigger biff, and comes from the funny old circus setup where a clown throws a cake into the face of another clown.

For so long, bulk wine has been synonymous with plonk – even in a country like Spain, where buying wine straight from the barrel was standard practice up until the 1980s, when it was largely replaced by bottles with certified designations of origin. We are well acquainted with the bad stuff, which we call vino peleón, literally “scrappy” wine, but thankfully, the era of its ubiquity is mostly over and done with. It’s much easier these days to find good wine at low prices (€1 to €5 per liter) that’s suitable for everyday drinking. And another upside to this practice is the environmentally friendly packaging: your own jug.

Churros, the long, skinny, crenellated, sweet fried crullers made from just flour, water and salt, have been enjoyed for centuries in Spain, with hot chocolate and without. However, in Barcelona, xurros, as they are called in Catalan, are becoming an endangered species. In recent years, more than half of the xurrerias in the city have disappeared. Many of the old-timer xurreros who still survive have the odds stacked against them: permit renewal for a street stall is near impossible; rent has become prohibitively expensive and continues to increase; or required updates to old infrastructure might prove extremely costly. However, we know of one young newcomer who has emerged with fresh energy and inspiration, incorporating lessons from the masters in his creative take on xurros. The best way to save this endangered species is to eat it, so here are our five favorite xurrerias, which make these star-shaped doughnuts with great care – and with delicious results that are worth seeking out.

Editor's note: Our third installment in the Global Bar Crawl takes us to Barcelona, where gin continues to be the drink of choice among locals. Tomorrow we head to a spot in Istanbul where you can spend an evening visiting a number of bars, all without leaving the building. Spain is a country that loves a long-drink – alcohol in combination with a soft drink, refreshing and open to invention and reinvention. On the heels of creative gastronomy’s efflorescence in recent years, many old drinks, cuisines and forgotten ingredients have returned, revived through new and more sophisticated techniques and interpretations. The gin and tonic, called gintonic here, is one such Spanish obsession, and all that ingenuity and focus have gone into taking this highball to the next level.

Morro Fi and Mitja Vida are two relatively new entrants to Barcelona’s vermuteo (“vermouthing”) culture, whose history stretches back to the turn of the last century. These two bars are the product of nostalgia for a bygone era fused with the social network- and urban design-driven present. The vermouth tradition in Barcelona was started in the early 20th century by Flaminio Mezzalama, who represented the Italian company Martini & Rossi in Spain, at his fabulous modernist Bar Torino. Vermut began to be produced in Catalonia, and in the following decades, the province developed its own style of the aromatic fortified drink. At the same time, the custom arose of having vermut before lunch with some pickles to whet one’s appetite. That tradition faded over time but has emerged in recent years as a kind of retro, hipster-approved pastime.

Fried pig’s ears fortified with garlic and parsley, veal cheek and tongue laced with vinaigrette, hefty veal and pork meatballs, creamy artichoke or eggplant omelets or a hearty bocadillo of marinated tuna, red pepper, anchovies and olives: these esmorzars de forquilla, or “fork breakfasts,” are how a Catalonian might start his day – especially at Can Ros, a tapas-and-bocadillos joint that’s open every day from 7 a.m. until midnight. Office workers might drop by for a coffee at mid-morning, followed by the lunch crowd, which takes over from 2 p.m. to 4 p.m. Dinner, of course, lasts well into the night. It’s breakfast, however, that has made Can Ros most popular among locals.

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.

Now that ski season has begun in Catalonia, thousands of Barcelonans make the pilgrimage every weekend to the Pyrenees. But winter sports are not the only draw; this is also the time to enjoy the cooking at masias, traditional farm buildings that have been converted into restaurants.There, the smells of winter stews and dishes made with mushrooms, game, mongetes (beans) and butifarra (a kind of pork sausage) are motivation enough to arrive at the village early and in one piece.

When we think of white wine in Catalonia, we think of its seemingly endless possibilities. Production of whites here has a 2,000-year-old history. The wide-ranging diversity in the area’s Mediterranean climate and calcareous soils, from the mountains to the sea, and the combination of old grape varieties and newly introduced “foreigners” with traditional and experimental methods of production make for innumerable styles and no taboos. Who knew white was a color with so many variations? The traditional Catalan grape varieties used to make white wine are mainly macabeo, xarel-lo, parellada and garnatxa blanca, but this area of Spain has the largest number of white grapes included in all its protected appellations (D.O.). Where other Spanish D.O.s usually are deeply defined by one or a few varieties, in the Catalunya D.O. there are more than 16 allowed – 35 counting the reds. In fact, this umbrella appellation, which covers wines that do not fall under the 10 subregion designations (Montsant, Penedès, etc.), was created to allow the use of all the grapes of the other Catalan designations in the entire area. It implicitly gives freedom to Catalan winemakers to express more than the old narrower conceptions of terroir and opens the doors to experimentation.

Mushroom hunting has an irresistible, magical pull. Composer John Cage, an avid mushroom collector, found them an integral part of his creative process, once writing: “Much can be learned about music by devoting oneself to the mushroom.” Every fall, thousands of Catalans likewise find themselves under the mushroom’s spell, following the elusive fungus’s silent melody into the woods, a rustic wicker basket in one hand and – more and more these days – a GPS-enabled smartphone in the other.

At first glance, Bodega Manolo seems like the usual wine shop/tapas bar that Barcelona does so well: a solid place to replenish our wine stocks from the barrels, quench our thirst with a cold caña or satisfy our hunger pangs with a vermut and a tapa or two of oil-drenched anchovies. None of which sound too shabby. However, we know to venture through to the rear, where, at dinnertime, the brilliant white tablecloths reveal the venue’s greater ambitions.

Anouchka hails from Extremadura, land of jamón and some of Spain’s best dry-cured sausages. Julien is French and an expert on wine. Together, the husband and wife run La Perla de Oro (“The Gold Pearl”), a pint-sized former colmado (old-style grocery) just off Las Ramblas, where top-notch bocadillos, or baguette sandwiches, are just one of many attractions. Since opening in 1939, three generations at La Perla have supplied their Raval neighbors with cured sausages, cheeses, preserved foods, salted fish and dried legumes. They became known especially for their bocadillos.

Legend has it that in 12th-century Priorat, in the region of Tarragona in southern Catalonia, there was a shepherd who dreamt every night of a ladder leaning against a pine tree. The ladder ascended from the valley all the way to heaven and angels climbed up and down, tending to their heavenly and earthly duties. Some Cistercian monks, upon hearing this story, took the vision as a divine message to build the monastery Scala Dei (“Ladder of God”) in that very spot. Those clever monks, noting the angels’ comings and goings, decided to become their wine suppliers and began cultivating grapes and making wine there.

[Editor's note: We're sorry to report that La Biblioteca Gourmande has closed.] In the heart of El Raval, one of Barcelona’s most multicultural neighborhoods, lies a portal to the Catalan countryside. At La Biblioteca, which opened in 2012, the origins of the ingredients sing out clearly from each dish and plunge you into a pure culinary experience inspired by the land: the traditional farmhouses called masias, the rustic recipes of the Pyrenees, the perfume of the valleys and gardens, the modern farmers near the city and the influence on plants and herbs of the Mediterranean Sea.

Most people who visit Barcelona are sure to spend at least some time at one of the city’s beaches. Yet few are aware that when seeking respite from the bustling urban streets, heading up into the forested hills above the city can be just as pleasant. Vallvidrera, a village at the entrance to Collserola National Park that offers gorgeous views of the surrounding forests and the city below, is just the place for such an excursion. Starting in the early 19th century and up until the 1980s, Vallvidrera served as a vacation destination for wealthy Barcelonans who wanted to escape the summertime heat of the city. The abundance of mansions here, many built in the Modernist style, is a testament to this bygone era. Nowadays, although Vallvidrera is a year-round community that is technically part of Barcelona proper, it’s still a destination for local urbanites and their families wanting to get out of the city and relax, particularly on weekends.
