1/2 cup egg whites (from about 4 eggs), at room temperature
1/2 cup granulated sugar
1/3 cup confectioners' sugar, sifted
1 cup chilled heavy cream
1 half pint raspberries
Tiny mint sprigs or leaves, for garnish (optional)
Powdered sugar, for garnish
I use only egg whites and air which makes for an extremely light texture but completely crisp and dry rather than creamy or smooth.
