For a recent party we hosted
EDIT: Ingredients as asked—
Thinly sliced homemade sourdough baguette—toasted to make the crustinis. Very lighted brushed with some truffle oil at the end (and a sprinkle of MSG)
Crème fraîche
Prosciutto
Imperial ossetra caviar
Chives
Nice! But (always a but) my 2 cents: the prosciutto & caviar are enough to stand on their own. Ossetra is a great choice because it is (imo) a better flavor than Beluga.
