To serve, simply stick the caviar tin on top of a bed of crushed ice, and serve it with a bone, mother-of-pearl, gold-plated, or even plastic spoon. Do not use silver or stainless steel; both caviar and spoon will suffer.
Caviar may be piled on blini (see recipe) or on toast points or plain bread. Accompaniments include melted butter, minced green onions, finely chopped hard-cooked eggs (whites and yolks are kept separate), sour cream or creme fraiche, and lemon wedges. Fine caviar, though, is extravagant enough on its own, and we like it best unadorned.
