Barcelona’s food shops and colmados offer culinary treasures all year long, but the holidays are a particularly exciting time for browsing their wares. The festive window displays show magnificent gift baskets overflowing with tasty treats – with many Spanish and Catalan specialties among them. Perhaps the most desirable items in holiday gift baskets here are the seasonal sweets, which previous generations would amass in quantities that would serve as “emergency” treats for unexpected guests the rest of the new year. (Thankfully, one can now find these year-round, so there’s no need to hoard them.) We’ve written previously about artisanal turrón, which continues to be handmade by a few family-run companies.

At the beginning, Gelida was just a bodega where Joan Llopart i Figueres, who came from the village of Gelida in Penedés, offered Catalan wine, cold cuts and a few traditional Catalan dishes cooked by his grandmother, like butifarra amb mongetas (boiled sausage with beans). Llopart i Figueres and his wife worked here until they were in their 80s. They were succeeded by their two children, Teresa and Alberto, who have always been involved in the family business and who continue to run the place today alongside their respective spouses, Josep and Luci. Alberto and Luci’s son, Gerard, helps to manage the restaurant, and Laura and Santi, family friends who live nearby, joined the team in recent years as dining room manager and chef.

In Istanbul's iconic Haydarpaşa train terminal, the door of a crowded restaurant and bar opens to beams of sparkling light streaming across the Marmara Sea coast. Trains haven't departed Haydarpaşa for nearly three years while the station undergoes extensive renovations, but its restaurant, Mythos, is still open and popular as ever, a refuge for a faithful crowd of regulars, who come to drink at a train station even though they aren’t going anywhere. Built in the first decade of the 20th century by the Germans and gifted to Sultan Abdülhamid II, the station is a handsome and prominent icon of the city, an imposing presence on the city's Anatolian shoreline.

Three humble ingredients – potato, cabbage and bacon – that’s all it takes to cook trinxat, the quintessential Catalan wintertime comfort dish. Potatoes and cabbage are boiled and mixed with fried bacon, and everything is cooked as a mash in a pan until it resembles a potato omelet. Its simple ingredients and even simpler preparation are exactly what make this dish so delicious.

Büyükada has long been a popular destination for İstanbullus seeking a break from harried metropolitan life. With its array of quaint köşkler (Ottoman-era wooden mansions), walkable woods and relative quiet (automobiles are prohibited, so there’s none of the modern world’s ubiquitous, underlying machine hum), this five-square-kilometer island, about an hour’s ferry ride southeast of the city center, serves as a welcome counterpoint to the bustle and bother of existence in an urban agglomeration of 14 million. There’s just one problem: The dining scene is insipid. There’s no shortage of fish restaurants along the esplanade, just east of the ferry terminal, but in our experience they’re undistinguished – indeed, indistinguishable – and maddeningly overpriced: in short, tourist traps. Some of the boutique hotels offer reasonable, if unexciting, fare on-site, but if you want to dine out, that row of uninspired seaside eateries is the only game in town.

With all the talk about the benefits of quinoa, chia seeds, goji berries and similar superfoods, we can’t help but be a little taken aback when Dolors, one of the owners of the restaurant Can Vilaró, explains the benefits of eating cap i pota, a traditional Catalan stew made with calf’s head and leg and chickpeas. According to her, the gelatinous chunks of meat make the skin glow and fight wrinkles. “It works as well as the most expensive collagen facial cream available at stores,” she says with a cheeky smile.

We like to think of İnciraltı, a laid-back meyhane in the sleepy Bosphorus-side Beylerbeyi neighborhood, as a destination restaurant – not so much because of the food, but because of the destination itself. Not that there’s anything wrong with the food here, which is reliably well made. The meze tray at İnciraltı (which means “under the fig tree” in Turkish) is brought to your table carrying all the classics, plus a few welcome and tasty surprises, such as the zingy brined twigs of the caper plant and a sea bass fillet that has been cured in a piquant sauce redolent of curry.

Kim Díaz, a well-known local restaurateur and owner of Bar Mut tapas bar and El Mutis cocktail bar, wanted to pay tribute to one of the most humble and sadly underrated Spanish snacks, the sandwich. Sandwiches are generally made by most Barcelonan bars with defrosted cheap bread and greasy fillings, and good ones are not easy to find in the city (though we have written about some great ones). Entrepanes Díaz opened last February with the goal of giving the sandwich the respect it deserves.

Reviewers are often tempted into using metaphors that portray the restaurant as a sacred place -- the sushi temple, a t-bone pilgrimage, chili-cheese fry heaven. But in Istanbul’s Moda district on the Asian shore, we’ve found a praiseworthy fish restaurant that could justifiably be described as a shrine – literally. For more than 50 years, a local Greek family has been serving saints and sinners alike at Koco, a rambling seaside fish house situated atop an ayazma, or sacred spring. There’s meze and fresh grilled fish with raki upstairs, candles and a shot of holy water downstairs. Judging by the size of the dining room, Koco is preferred by very large groups. One recent weeknight, though, there were just enough customers to fill in the tables lined along the windows. The view of the old Moda ferry dock and the Marmara Sea from the window side of the room is excellent but leaves you leagues from the coat check where the staff hangs on a slow night.

Editor’s note: The year is coming to an end, which means it’s time for us to look back on all the great eating experiences we had in 2014 and name our favorites among them. Can Pineda At this tiny, century-old restaurant in the neighborhood of El Clot, we ate a simple dish of guisantes lágrima (“tear-shaped peas”) with little bits of jamón ibérico, one of the most delicious culinary treasures we have had all year – and one we will remember for a long time to come.

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.

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.

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.

On a night out in Istanbul, we often find ourselves forced to make sacrifices in one or more categories of the overall dining experience. Great food at reasonable prices will surely be laid out in a room decorated in Anatolian kitsch.

In Spain, conservas, or foods preserved in cans and jars, are not simply a matter of economic survival or a source of basic nutrition for students, hikers, military recruits and the like. Rather, the tradition of conservas more resembles that of keeping one’s most beautiful jewelry locked safe in a strongbox, to be brought out only on special occasions like Christmas, birthdays or the victory of a favorite football team. There’s nothing better than some delicate canned cockles to lavish on your parents-in-law before a holiday meal!
