Does anyone know of any Argentine groceries in the Cambridge/Somerville area? I'm looking specifically for a special kind of provolone cheese used for grilling--to create provoleta, a simple argentine app of the cheese, grilled with olive oil and oregano. The argentines create a thin crust which keeps the cheese together, while melty in the middle when cut. When I make it with regular provolone it melts all over the place, so I'm searching for the special cheese. I'd appreciate any help. Thanks!
