Reviro
For field workers in the yerba-mate plantations of Misiones, the morning starts with reviro: a simple dough of flour, egg, water and salt fried in plenty of fat and then broken up with a spatula as it cooks, until it becomes a pile of crisp, golden, irregular crumbs with soft centres. It is filling, cheap and very good dunked in a mug of mate cocido or milky coffee, and it shares its roots with the Guaraní and Paraguayan kitchen across the river. Traditionally it is fried in lard or beef fat; this version uses butter and oil so it is vegetarian. Turning it too early is the classic blunder: the batter needs to fry undisturbed until a crust forms, or it turns into a pale, doughy mash. Chef's tip: keep chopping and turning with the edge of a metal spatula for the last 10 minutes; the more edges you make, the more crunch you get.
