Origin
Cuor di Bue is the Italian oxheart, sold across southern Europe as a premium slicing tomato and named for its shape; the flesh is pink, dense and dry enough that it is used interchangeably for slicing and for sauce. The name, Bull's Heart, is shared across languages by a whole family of pink oxhearts, Bychye Serdtse, Coeur de Boeuf, Volovo Srce among them, which may or may not be the same tomato, so seed under any of these names varies.
