Brossat
Brossat, or brull in some zones, is a fresh cheese in Catalan cuisine made from whey (xerigot) resulting from the making of other cheeses, such as mató, a fresh or aged cheese, from sheep or goats.
It's made by heating the whey until the temperatures is almost but not quite boiling, when the insoluble milk proteins and other particles precipitate and can be collected in shape of white flocculuses on the surface of the whey.[1] It is not pressed, nor salted or aged, but is shaped with molds or cloths.
It is a cheese with very little fat (around 10%) and high protein.
Etymology
This product is called brossat in the Pyrenees, Menorca and Mallorca.[2] It's known and marketed as brull, in the contraforts muntanyencs of the Ports of Beseit, to the south of the lands of the Ebre and in Alt Maestrat.[3] This brull is used to stuff the flaó pastries of Morella.
