In Porto, francesinhas are everywhere. The monster-sized sandwich of white bread with steak, ham, cured cold cuts, and melted cheese smothered in a beautiful spicy sauce is a ubiquitous dish that says a lot about the city. When he first visited Porto, Anthony Bourdain asked after eating an entire francesinha with fries: "What is the rate of coronary disease in this country?" He didn't know at the time that, more than clogging the arteries, the beloved local dish warms local hearts. It also generates lively discussions. Every Porto inhabitant has their preferences: some like their francesinha with more sauce or even with a fried egg on top; others prefer different types of bread, from brioche to crusty bread roll. It is impossible, therefore, to reach a consensus on which venue serves the best francesinha in the city.

Just like at Porto’s central Campanhã train station on Rua da Estação, O Astro Cervejaria Petisqueira on the other side of the street is reliably crowded every day. Its strategic location near the station helps account for that. But what really draws the crowds in is O Astro’s reputation as a must-stop for the definitive take on the bifana, one of Porto’s signature sandwiches. Much like the train station, O Astro brings locals and visitors together from all over Portugal, in search of one of Porto’s essential bites. At the most elemental level, the bifana is a pork sandwich, and in its most traditional form it includes thin slices of braised pork shank tucked into a crusty roll called a carcaça.

When the late 19th-century Portuguese artist and cartoonist Rafael Bordalo Pinheiro wanted to create a vehicle through which to mock and criticize the country’s powerful elite, he settled upon the character Zé Povinho, an unsophisticated country laborer who served as a stand-in for the average citizen. While some Portuguese people took umbrage with their country’s everyman being depicted as a simple peasant, time has softened this criticism, and Zé Povinho has become something of a national icon. “Little by little, we started to see him with a certain tenderness, as a symbol of the Portuguese identity, a reminder of where we came from,” says Andrea Salomé, a restaurant owner in Porto.

With Marseille restaurants shuttered in the Covid era, many have transitioned to offering more takeout-friendly fare: namely, sandwiches. The hip bistro Cedrat’s 15-euro “hot fish” features a house-made fish sausage, poutargue (dried red mullet eggs) and seaweed. Michelin-starred fine-dining chef Alexandre Mazzia cures his own pastrami for a decadent, €21 croque-monsieur. Yet while high-end hoagies make fine once-in-a-while treats, we remain loyal to the old-school sandwich stand Chez Fanny. Located a few blocks up the hill from the Vieux-Port, this corner stand serves up fantastic sandwiches at phenomenal prices. The menu includes classics (think merguez-frites) and signature sammies that make the most of the region’s bounty.

You would think Sérgio Oliveira, the owner of Conga in Porto and the secret-keeper of its legendary recipe for bifanas, would be tired of the restaurant’s signature dish. But you’d be wrong. “As much as I try not to eat it, I cannot. It is impossible,” he says. "One always eats it; there is no chance not to.” It’s a simple but addictive dish. Pork, cooked all day in a mysterious spicy sauce and stuffed into a piece of bread that looks a bit like a roll– at first glance, it does not seem to impress. But Porto continues to hide the best and tastiest of its secrets in the simplest things in life.

Tomatoes, one of the joys of summer in most locales, thrive in Campania’s hot and sunny climate. Yet good tomatoes can be surprisingly hard to find in summer – the oval, longish, rather crisp varieties that are the region’s claim to fame are mostly used for cooking, and the best ones are canned or exported to richer parts of the world. Somewhat improbably, winter is the best time to eat fresh tomatoes in Naples. As soon as the days get shorter and the nights get colder, small cherry tomatoes with a distinctly pointy end start to appear at every vegetable stall and restaurant throughout the city – this particular version of the fruit is known as pomodorino del piennolo del Vesuvio, or simply piennolo.

Despite the image that Greece wants to sell the world as a holiday destination of eternal summer with beautiful beaches and clear water, the fact remains that it is a very mountainous country – almost a third of Greek land consists of hills and mountains. Most are forested, hosting a great diversity of ecosystems that offer fertile ground for mushrooms in particular. That said, mushrooms don’t feature prominently in traditional Greek dishes, and many people avoid them altogether, even the common cultivated varieties, from fear of getting sick. For many, meanwhile, mushrooms don’t evoke the best memories: During the 70s and 80s, the tinned variety was mainly used in cooking, as fresh cultivated mushrooms were rare and expensive.

Lunch at Casa Guedes is one of our favorite culinary rituals in Porto: After snagging a seat at the bar during the midday rush, we sit, mesmerized, as Mr. Cesar nimbly cuts slices of roasted pork shank, then places them on bread and moistens it all with his secret sauce. While not the only item on the menu, the famous sande de pernil (roast pork sandwich) is Casa Guedes’s raison d’être. After taking in Mr. Cesar’s entrancing sandwich-making choreography, we order the upgraded version of the sande, which is topped with gooey queijo Serra da Estrela, a creamy sheep’s milk cheese. Seating at this humble and low-cost eatery used to be minimal, and Casa Guedes’s popularity had long outstripped its capacity – fans could be found waiting patiently in queues stretching down the block.

Holiday traditions in Greece, like so much in that country, are rooted in ancient Greek and Roman customs – pagan, of course – that evolved through Byzantine times and were adapted with the advent of Christianity. More recently, the westernization of Christmas and New Year celebrations has made those holidays here look more like the globalized version of them, for better or for worse. Greeks like preserving their old traditions, however, and some customs still persist, even if many Greeks don’t know where they came from. The Christmas season, known in Greece as Dodekaimero (twelve days), officially begins on December 24, includes the celebration for the New Year and ends on January 6 with the huge celebration of Theophania (the baptism of Jesus Christ by John the Baptist).

You would think Sérgio Oliveira, the owner of Conga in Porto and the secret-keeper of its legendary recipe for bifanas, would be tired of the restaurant’s signature dish. But you’d be wrong. “As much as I try not to eat it, I cannot. It is impossible,” he says. "One always eats it; there is no chance not to.” It’s a simple but addictive dish. Pork, cooked all day in a mysterious spicy sauce and stuffed into a piece of bread that looks a bit like a roll– at first glance, it does not seem to impress. But Porto continues to hide the best and tastiest of its secrets in the simplest things in life. "It was my father who invented the famous bifanas with this wonderful sauce,” says Sérgio, who’s been running Conga the last eight years. It’s been more than 40 years since Manuel Oliveira returned to Portugal from Angola and opened the restaurant in 1976.

A gloppy, meaty, cheesy brick served in a pool of sauce and with a mountain of fries: please meet the francesinha, the culinary pride and joy of the city of Porto. Today, restaurant billboards proclaim in many languages that they serve the best version in the world, revealing the genuine power of this artery-clogging combination that, incredibly, was originally conceived as a snack. We have to say it though: eating a francesinha is worth every last calorie. This dense sandwich, which is impossible to eat just with your hands, is often considered the lusophone version of the croque monsieur.

Has mezcal gone the way of avocado toast, an item that’s become shorthand for cliched hipster trendiness? If you think yes, a visit to Mis Mezcales in Mexico City’s Colonia Roma may be in order. There, you will find Omar Trejo sitting behind his unassuming makeshift bar, parceling out sips to the uninitiated and reminding everyone who stops by his small liquor store devoted to small-batch Mexican distillates that before it became a “buzzy” spirit, mezcal was an elixir heavily-rooted in the soils and stories of Mexico. As Omar makes clear to those who come in, every bottle of mezcal tastes different, even from the same brand, the same agave variety and same year. It’s one of the drink’s greatest strengths and probably one of the greatest frustrations for drinkers who expect the standardization of tequila.

Feta must be one of the world’s oldest cheeses, it’s certainly one of the most famous, and it’s practically never missing from a Greek table, no matter the time of day. A person might grab a chunk of this chalk-white substance for breakfast, crunch through layers of feta-stuffed phyllo for elevenses, put a slab of it on her village salad for lunch, have it for supper along with a vegetable casserole and then pair it with watermelon for a scrumptious dessert. The only other food that a Greek may be even more addicted to is bread. If you were to guess which nation boasted the most cheese eaters on the planet, surely you would say France, home to so many delectable and sophisticated fromages.

You might not have heard of trahana, sometimes called rustic pasta, if you don’t possess a Greek grandmother. This humble food rarely turns up in tavernas, yet it is a staple, especially in the winter months, and the basis of many a comforting meal. In fact, it may just be the world’s first instant soup. Trahana, which is most often seen in small couscous-like pellets, represents a synthesis of wheat and dairy, making it more nutritious and tastier than ordinary pasta. Its flavor and consistency depend on whether the flour, semolina or cracked wheat is kneaded with milk, soured or fresh, or yogurt. Traditionally, the mixture would be shaped into balls or patties, dried in the sun until hard, grated into tiny granules, dried some more, and then stored in cloth bags, where it would keep for months, even years.

After being named Best European Destination in 2017 and earning a few other tourist distinctions, there’s no doubt about it: Porto is trendy. But what’s trendy is also in Porto, and those who live here see new restaurants pop up every week. We try them all – places both bold and familiar – because we have a good appetite, but we put our trust in those spots where we get the warmest reception. And trust is something we take very seriously in Porto. Homey meals at A Cozinha do Manel Open now for three decades, A Cozinha do Manel is far from the touristy downtown and serves up good old comfort food, the type of fare that leaves us serenely satisfied.
