Pisco is a brandylike liquor, popular in South American winemaking regions. My favorite kind is made from fragrant muscat grapes — perfect for a blood orange pisco sour.
3 ounces pisco
1½ ounces simple syrup
Juice of ½ blood orange
1 egg white
Freshly grated black pepper
Fill a cocktail shaker with ice and add pisco, simple syrup, blood orange juice, and egg white. Cover shaker and shake vigorously for 1 minute. You want the egg really frothy.
Strain cocktail into a rocks glass, top with a grating of black pepper and serve immediately.
