Sanduíche de mortadela
Tourists queue for it at the Mercado Municipal in São Paulo, where the sandwich counters on the mezzanine fold slice after slice of mortadella onto a hot griddle until the stack is taller than the bread. Mortadella is a cooked pork sausage, and warming it this way crisps the edges, softens the fat and makes it taste sweeter and more peppery; a layer of melted provolone or mild cheese glues it together inside a crusty French roll. It is gloriously over the top, best eaten with both hands and a paper napkin. The mistake most people make is stacking cold mortadella flat, which stays rubbery; fold the slices loosely so the heat gets between them. Chef's tip: ask for the mortadella sliced very thin, almost see-through; thin slices ruffle up and give the sandwich its height and tenderness.
