Refreshing and colorful, this is an ideal aperitif for a cocktail party or Italian dinner. Aperol, a liqueur made from bitter and sweet oranges, herbs and roots, adds citrus tang with a touch of bitterness so beloved by Italians. Make a pitcher-full for a party.

Pour Prosecco in a stemmed wine glass filled with ice. Add Aperol and top with club soda. Garnish with an orange slice.
