Asking cariocas if they remember their first Biscoito Globo, the ubiquitous, crunchy beach snack, is like asking anyone who teethed in the United States if they remember trying Cheerios for the first time. Globo biscuits and sweet iced mate are to Rio's beaches what hot dogs and beer are to American baseball stadiums. Calls of “Ó Globo! Ó mate!” are the soundtrack along the shores of Copacabana, Ipanema and Leblon. The iconic packaging, which features a globe-headed mascot surrounded by the Eiffel Tower, the Tower of Pisa, Portugal's Belém Tower and Rio's Sugarloaf, has been reproduced on t-shirts, tote bags, and cangas (sarongs).

Carioca summer culture is dictated by the heat. It’s courteous to ask guests if they’d like to take a quick shower upon arriving at your home (because everyone takes multiple showers a day in the summer). Beer at parties must be estupidamente gelado. Movie theaters sell out even for so-so films because the air conditioning inside is delícia. This year, the Rio city government took the bold step of legalizing the use of knee-length shorts for city employees and bus drivers during the summer. Four other critical ways that locals chill out are: sorvete (traditional ice cream), picolé (popsicles), gelato and sacolé (anything frozen in a plastic sack).

As an electrician in the Galeão international airport, Emerson Gama responded to emergencies like exploding transformers. But in his spare time, he was becoming a self-made expert on Latin American mythology, tropical ecology and sustainable resource management. These passions led him to quit his job four years ago; since then, Gama has become the Rio de Janeiro chocolatier with the most dedicated cult following. Only a few South Zone specialty stores carry his Quetzal chocolates, and where they come from is largely unknown, both to the clients on the long waiting lists for deliveries and to Gama’s own neighbors. The “secret” source?

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.

It’s hard to find a “backstreet” in Ipanema, Rio’s pricey, posh epicenter of tourism, where real estate is prime and snack bars charge twice the price of grubbier places elsewhere. But leave it to three Frenchmen to open a wine bar that sincerely strives to be – and succeeds in being – a Brazilian boteco in the city’s most iconic beachside neighborhood. The bubbly trio Vava, Laulau and Gerard saw in an old construction supply store near the Ipanema metro stop an opportunity to create an upscale bar with the charm (and, believe it or not, the prices) of a Rio neighborhood eatery.

Editor’s note: This post is the third installment of “Best Bites of 2013,” a roundup of our top culinary experiences over the last year. Stay tuned for “Best Bites” from all of the cities Culinary Backstreets covers. Bar do Adão There are so many good fillings – 65, in fact – for the pastéis, or fried turnovers, at Bar do Adão that we appreciate their diminutive size, which allows us to eat a greater variety in one sitting.
