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.

There has always been a bit of a rivalry between the two main cities of Portugal, Lisbon and Porto, which is well illustrated by an old running joke among some tripeiros (the name given to the people of Porto): whenever someone asks what is the best thing about Lisbon they will reply, “The highway sign that says ‘Porto.’” But it’s a healthy rivalry for the most part – football aside. Lisboetas, Lisbon locals, in general even tend to recognize that the food might actually be better in Porto and its surroundings, especially traditional dishes. While Porto does not benefit from the same multicultural influences that helped shape Lisbon’s restaurant scene, it is home to some very talented cooks with a knack for doing so much with so little.

Porto’s very old and emblematic Bolhão Market has been under renovation since May. Now working in a temporary building, the market vendors are feeling a mix of enthusiasm and apprehension about the new structure – they are mostly concerned with how different it will be and how much tradition will be lost.
