The Delta de l’Ebre is a magical part of southern Catalonia’s Tarragona region. A flat swampy area where the Ebro River meets the sea, the delta contains within its confines a natural park rich in fauna and flora as well as 20,500 hectares of rice fields; the ecosystem allows both to coexist in harmony. The area is perhaps at its most magical when the water rises up to cover the plots, creating what the rice producer Teresa Margalef calls a “land of mirrors.” Until the arrival of the Arabs to the Iberian Peninsula in 711, rice in Spain (and Europe) was a non-cultivated grass with Asian origins; wheat was the crop of choice. The Moors, experts in its cultivation, started to implement their planting and harvesting techniques in the swampy areas in the south and east of the peninsula.

The rain makes it feel like November, when the majority of Spain’s olive oil producers begin the harvest to make extra virgin olive oil. Yet it’s October, and we’re watching the gathering of Arbequina olives in Belianes, very close to the city of Lleida in central Catalonia. These beauties are mostly green, with a few already changing to purple. Jose Ramón Morera, one of the owners of the small company Camins de Verdor, is finishing the harvest of these green olives for Umami, their premium line of olive oil. An absorbing deep green color, the organic extra virgin olive oil is intensely aromatic and fruity, made from early harvested oils that are mechanically pressed using a traditional cold extraction method.

With almost 6,000 kilometers of coast (5,978 to be exact), Spain is the world’s second largest consumer of fish and seafood per resident (the first being, no surprise, Japan). Bathed by the cold Atlantic on one side and the warmer Mediterranean on the other, the country harbors a wide variety of habitats that have made it easy to source many different species of marisco (seafood) and fish. While these fruits of the sea are available at all kinds of Spanish restaurants and bars, the best way to guarantee a magnificent seafood feast is to go to a proper marisquería. A perfect example is La Barca del Pescador.

Low in fat and calories and rich in minerals and proteins, the snail is an old staple with a newfound popularity – while perhaps not as obsessed as the Romans were, Catalans are rediscovering all the benefits of snails: they’re nutritious, tasty and easy to raise. We sample some on our Made in Catalonia walk in Barcelona.

“The future is the past,” says Salva Serra, quoting winemaker Pepe Raventós, the latest in a long line of winemakers to run the famed Raventós i Blanc. While his lineage might not be quite as storied, Salva knows a thing or two about preserving the past – the Serra family has owned La Perla BCN, a restaurant located in the upper Poble Sec neighborhood, very close to Montjuïc Park, since 1965. It’s the type of old traditional restaurant that you only learn about from word of mouth – a friend who only went there because another friend told him about it. The wonderful area where La Perla BCN is situated, with the Poble Sec residential neighborhood on one side and the nearby gardens of Montjuïc hill, home to museums and theaters, including the Grec Theater (built for the Universal Exhibition of 1920), on the other, was not always so charming.

As the food scene in Barcelona continues to change at a rapid clip, with a constant stream of closings and openings, the city’s bodegas are an excellent example of what can be saved. These are businesses that have been updated again and again, sometimes over the course of a century, in order to preserve an essence and an identity that nobody – not now nor back then – wants to lose. La Moderna, a tapas bar and bulk-wine shop on Carrer d’Enric Granados in the Eixample Esquerra (Left Eixample) neighborhood, is a good example of this preservation model. Established in 1937, the bodega has survived just about everything, including the Spanish Civil War (1936-39).

“Now we finally have light!” a vendor excitedly tells a customer, one of many similar exclamations we overhear while wandering around the new temporary digs of the Mercat de L’Abaceria Central. Formerly housed in a historic building on Travessera de Gràcia in the Gràcia neighborhood, the market and its 56 food vendors, 43 food stalls, 13 clothing and kitchenware merchants and two cafeterias recently shifted to a nearby location as renovation work begins on the original structure.

We’re counting down the days until September, which is when many of our favorite bodegas in Barcelona will open their doors once again and we can settle in for a vermut and some of this delicious jamón ibérico.

There we are at Bodega Carlos, enjoying a homey and delicious batch of crispy fried anchovies and succulent stewed pork cheeks, when we suddenly hear birdsong. We look up, but neither canary nor nightingale can be seen flying around the high-ceilinged bodega-restaurant. But then the birdsong instantly switches to a sound we can best describe as a falling whistle, like the one that accompanies Wile E. Coyote as he falls from a cliff. Is it a bird, is it a plane, or is it a smartphone ringing with infinite improvised melodies? No, it is Carlos Estrada Roig, the owner of this friendly neighborhood bodega and an expert whistler.

For some inexplicable reason, leche merengada, or meringue milk, a traditional Spanish summer drink, has fallen out of favor over the past few decades – industrial ice creams and sodas, with their multicolored flavors, bubbles and fantasy frozen shapes, have seduced local palates, making this monochrome drink pale in comparison. Well, we say that it’s time to shine the spotlight back on the démodé but delicious and nutritious leche merengada and to revive a drink that was considered opulent in numerous Spanish cities back in the 19th and early 20th centuries, and documented in recipe books from as early as the 18th century.

An employee at Sirvent tops the shop’s artisanal ice cream with bright red candied cherries. Sirvent is one of Barcelona’s turronerías (also called torronerías), so-called because they dedicate themselves to making artisanal nougat (turrón) in the winter. But come summer, many flock to them for a cooling ice cream or horchata.

Cal Pep is a name you’ll find across Barcelona, but it takes on a different meaning depending on which neighborhood you’re in. In Gràcia, the name Cal Pep is synonymous with an old bar-bodega, dedicated almost entirely to the business of drinking (Carrer de Verdi, 141). The Cal Pep in Born is a famous seafood restaurant in Born (Plaça de les Olles, 8), with lines snaking out the door. In Sants, Cal Pep is affixed to a charismatic bodegueta (small bodega). Narrow, long and dimly lit, this particular Cal Pep has the atmosphere of a wine temple – including wooden casks and a vintage fridge – that has been frozen in time, with most of the original decorations from 1927 still intact.

The peripheral neighborhoods of Barcelona – untouched by tourism and with cheaper rents – are a land of opportunity for chefs seeking an affordable place to set up shop. These areas in turn attract gourmet gold seekers in pursuit of a brilliant meal at a friendly price. In the residential streets of Sants, not too far from the city’s main train station, one restaurant shines particularly bright, with its eclectic style, influences and, of course, flavors: MinE. MinE is a combination of combinations, beginning with the owner and head chef, Martin Parodi. Born in Buenos Aires, Parodi is the son of a Japanese father and an Italian mother. He grew up in Barcelona, studied in France and then worked in a number of European countries.

Horchata, a unique and deliciously refreshing concoction made from chufas (tigernuts), water and sugar and served chilled, is beloved across Spain. In Barcelona, there’s really only one place to try the stuff: Horchatería Sirvent. The faithful line up here in droves during the summer months, waiting with ticket in hand to sip the best horchata in town.

“I still don’t know where the siphon bottles for the vermut are,” says an employee of Marina, a small bar in the newly renovated Mercat de Sant Antoni. It’s clear as we’re walking around that the staff of the market’s few bars and its many vendors are still settling in and adapting to their brand new spots. At the same time, hundreds of visitors have been exploring the revamped market each day since its opening last week asking, “Where can we eat or drink something?” So far, that seems to be the question on everyone’s mind, particularly locals. But this is not another food hall, this is a proper neighborhood market focused on selling quality fresh produce and other food product
