In this Italian dessert, scoops of ice cream are doused in espresso (or sometimes a liqueur). Hence the name gelato affogato, "drowned ice cream."
Beat cream until soft peaks form.
Place 2 scoops gelato into each of 4 glasses. Pour 1/2 cup hotespresso over tops of each, just to cover. Top with whippedcream, and serve with biscotti if desired.
