The best appetizers are full of flavor, fun to look at, and, ideally, take very little effort to prepare. Vegetable crudites fit those requirements but they aren't exciting.
A delicious appetizer--albeit one for those without caloric restrictions--is a piece of prosciutto with a slice of triple cream and a topping of fig puree. The key to this dish is using high quality ingredients: Saint Andre triple cream, a good Italian prosciutto, and ripened farmers' market fresh figs.
The prosciutto can be rolled up but leaving it open is visually pleasing. Anyone picking one up will naturally do the rolling themselves.
Delicious any time of day: for breakfast, a light lunch with a salad, or in the evening with cocktails and wine.
