Francesinha is a Portuguese sandwich originally from Porto, made with bread, wet-cured ham, linguiça, fresh sausage like chipolata, steak or roast meat and covered with melted cheese and a hot thick tomato and beer sauce served with french fries.
It is said that the Francesinha was invented in the 1960s. Daniel da Silva, a returned emigrant from France and Belgium, tried to adapt the croque-monsieur to Portuguese taste. Other versions date the Francesinha to the 19th century. It is a very popular dish in Porto and is connotated with the city, although it can be sometimes found elsewhere in Portugal. A classic francesinha meal would include the sandwich, surrounded on a bed of chips doused in the famous sauce, and complemented with a fino, literally meaning thin or fine, which in this context refers to draught beer.
