Anyone with observant eyes and a rumbling stomach will notice how newcomers to the city – and their snack foods – are cropping up like the pink beijo-turco flowers that grow in Rio’s forests after a heavy rain. There’s Hasan with his eggplant esfiha pastries amongst the popcorn vendors and candle-lighters at the Nossa Senhora da Glória church of Largo do Machado; energetic and trendy Armin with his falafel in Botafogo; tired Hafez with his boxes of savory snacks, trying to find shade on the Rua das Laranjeiras. Brazilians didn’t need to be told to like Arab food, and now they’re getting a fresh wave of that culture’s already iconic snacks. The bready esfihas and bulgur wheat kibe may be to Brazilians what chicken tikka masala is to Brits, a formerly foreign food now amongst the country’s most ubiquitous for drunk munchers and rushed lunch-breakers alike. Arab migration dates back over a century in Latin America, and Brazil’s Lebanese diaspora is the largest in the world, with a population as high as 10 million. Some 10 percent of Brazil’s congress is of Arab ancestry.

Geography-challenged foreigners often come to Brazil with a vague, ill-informed hope of finding good Mexican food. In Rio, that only happens at Ipanema’s Azteka. In fact, there are few restaurants we find as compelling in the touristy beachside neighborhood as this one, focusing on Tex-Mex cuisine adapted slightly for Brazilian palates. The breadbox-sized eatery was established by Miguel F. Campos and his Bulgarian wife, Aglika Angelova, a professional piano teacher, after the couple scouted out a new country in which to start a new chapter of their lives together. The two met at an organic pizzeria in Chicago.

Arataca boasts a title so extraordinary that, were it more widely known, we would expect the modest Copacabana snack bar to be covered with colorful Nossa Senhora do Bonfim blessing ribbons so that generations of pilgrims could light white, tapered candles and lay baskets of offerings at its sidewalk entrance. That designation is: First Açaí – the Amazonian superberry – served in Rio de Janeiro. Local lore says that the slushy, purple drink was first served here 59 years ago, and it was a hit. Nowadays, you’ll see cariocas all over the city with the drink’s trademark ink-stained teeth. Arataca was opened by two immigrants from the northeastern state of Pernambuco. One was in the military and, in his travels through Brazil, he developed a taste for the highly unique cuisine of the country’s north, particularly that of Pará state, considered the gateway to the Amazon region. Pará is also the cradle of the Amazonian berry açaí, which is sold in barrels at riverside marketplaces in the commercial and political capital of the state, Belém.

In the anything-goes lead-up to Lent, Carnival in Rio is as much about public inebriation and bawdy public displays of affection as it is about extravagant costumes and entertainment. It’s also a time when freelance moneymakers can largely evade municipal guards by dressing up in costumes as fanciful as any carnivalgoer while they sell their homemade alcoholic concoctions unlicensed. Carnival is early this year – Ash Wednesday is February 10 – which means the city’s sinning is in full swing from now onward. Culinary Backstreets scouted out some of the alternative alcohol options you’ll find on the streets this time of year, ones both classic to hundreds of themed street-party blocos and some that seem to be one-of-a-kind offers.

An employee of the popular bulk goods seller Casas Pedro slices up a bacalhau, a codfish beloved by Brazilians and a keen Portuguese culinary influence.

Watching residents of Paquetá Island between the turnstiles and gate to get their ferryboat home from Rio’s central Praça XV port is like watching horses chomp at the bit before their stable doors are opened. The 5,000 proud homebodies of Rio’s little car-less island in the center of Guanabara Bay are anxious to get back to it, often pulling tall shopping carts stacked with beer and snacks. There’s only one small grocery store on the island and what gets here, gets here by boat and human hands. The ferry is a destination as much as a journey for those who want to appreciate one of Rio’s most unique little corners. You’ll question the quiet here and remember that this city of 14-lane highways is set to a constant soundtrack of engines and “PORRA!” (Pronounced POU-hah, this is a ubiquitous carioca curse you’ll hear when someone’s mildly upset or surprised, a much saltier version of “damn it!”)

Though Brazil is rich in mother earth’s most colorful produce – like passion fruit, guava, papaya, collard greens and sweet abóbora pumpkins – residents of Rio nonetheless have a steady love affair with hot dogs, which are pronounced “HOH-tchee DOH-geey,” or literally translated into Portuguese as cachorro quente. Vendors across the city pile the bunned favorite with a set of toppings as elaborate as they are consistent from one cart to the next: hard-boiled quail eggs, green peas, corn, potato straws, stewed onions and Parmesan cheese. “Tia” was a young mother of three with a husband whose blue-collar salary as a cop meant life was a hustle in their working-class neighborhood of Freguesia. “I had to take them all to school, prepare breakfast, the school uniforms,” she said. “I got no rest.” Her hot dog vendor days began in 1982, when her daughter was a newborn, and she had what she now says were two decades of busting her chops before the cachorro quente da Tia would become one of the most in-demand snacks in this periphery neighborhood of Rio. “Thank God,” she says of her success in her hot dog business, which now encompasses both a quiosque and a store, with 16 employees in total.

Tapioca—a chewy pancake and tasty street snack staple in Rio made from yucca root, which is widely used in Brazil. One of the many humble, delicious snacks to be found while wandering Rio's streets.

You get to Bar do Alto by taking a zippy mototaxi up the snaking streets of the Babilônia favela and then walking 10 minutes up jagged staircases that eventually bear right. On the route, you’ll pass by slices of life that make favelas a museum of Rio, where the city’s symbols and icons are on display in the bare and human way that’s made possible by close quarters of self-made dwellings. There are the evangelicals raising their voices in weeknight prayers. Shirtless men with leathered skin that speaks to long day jobs, now tipping back tall evening bottles of beer. Children playing soccer as overheated cops in bulletproof vests slump on nearby benches.

Editor's note: As Rio gears up for the 2016 Summer Olympics, CB has been exploring the backstreets of the city's Olympic Zones in search of gold-medal eateries. This is the first dispatch in the series. Barra da Tijuca was meant to be the best of Rio without its worst. Sandy beaches with no pickpockets. Top-notch shopping with no annoying squawking vendors. Playgrounds with no worrisome outsiders – because those playgrounds are inside gated condominiums with guards who sometimes have pistols tucked into their belts. The Avenida das Américas is 14 lanes wide, enough space for everyone to have their own car and leave the bus lanes to the white-uniformed maids and servicemen and women who bustle into Barra each day.

Editor's note: To give 2015 a proper send-off, we're taking a look back at all our favorite eating experiences of the year.

On a Monday at 1 p.m., private equity investor Nargilla Rodrigues and her two colleagues bring a fourth co-worker to the Rotisseria Sírio Libanesa in Rio’s Largo do Machado neighborhood to initiate him to their weekly lunch ritual. An army of diners in business attire have packed the small restaurant and clump around the to-go counter. Rodrigues grabs a standing table and fires off an order of stuffed cabbage leaves, kafta and lentil rice like they are shares in a fire sale.

Erisvaldo Correia dos Santos dreamed of being a star. He saw himself as a humorist, a singer maybe, and most certainly an artist. But the scrabbling northeastern immigrant came in 2005 to Rio, the Brazilian city of dreams, with just 20 reais – about $9 – in his pocket and a family to feed. “When I came here, I was hard as a coconut,” dos Santos says, meaning he was hard-up for cash. Nothing a little self-deprecation and naughty jokes couldn’t make up for. Food and guilty pleasure have a long, intertwined history, going all the way back to Adam and Eve. In that vein, snickering Brazilians have long appropriated the verb comer ("to eat") to mean a more carnal type of consumption. Rosca, the word for “screw,” has been turned into something even more blush-worthy, referring to other, fleshier things that can be screwed, and is also used to refer to a nicely round doughnut.

Rio de Janeiro didn’t need to be told to host colorful outdoor fresh food markets. The feira is a carioca tradition, with wooden booths going up overnight at their weekly locales and filled with wares so standard any local could recite for you off his head what you can and can’t find there. But with a little kick from the tools of the digital age and a hipster-era recalibration of the local palate, the Rio feira has gotten a particularly nice new edition. Junta Local brings together local producers and budding chefs in a biweekly, rotating-location food-fest, often accompanied by live music.

If you go to Rio’s Café Lamas to see where leftist organizers met during Brazil’s military dictatorship, go to Majórica to eat steak where the city’s business and political elites gather today. Located on a residential street in Rio’s Flamengo neighborhood, the restaurant from the outside looks like a three-story house, but for the neon red cursive sign with its name. It was founded in 1963 by two brothers from the Spanish island of Majorca and is now owned by the daughter of one brother, together with 79-year-old Galician-born Ernesto Rodriguez, who worked his way up from being the restaurant’s janitor 50 years ago.
