Bizcochitos de grasa
A paper bag of bizcochitos de grasa sits next to the mate gourd in kitchens, offices and roadside service stations across Argentina, from Buenos Aires to the Andes. These little rounds, a couple of bites each, are layered with beef fat, so they flake and crumble, salty and plain enough to eat by the dozen with bitter mate in the afternoon. The fat is rendered beef fat (grasa vacuna), so they are not vegetarian; ask your butcher for dripping or render suet yourself. A dough worked too warm is the mistake that robs them of their layers; the fat melts into it instead of staying in sheets. Chef's tip: chill the dough for 10 minutes between folds whenever it starts to feel greasy, and prick each round right through so it puffs in flakes rather than domes.
