Sort of a three-ingredient cranberry nog?
You can use pasteurized eggs if you’re worried (though I wouldn’t be), but be aware that pasteurized egg white don’t hold a foam as well. Risk versus reward, I guess.
Cranberry Foam Cocktail
2 cups cranberry juice
1 egg white, beaten stiff
Add cranberry juice to egg white; beat until foamy. Chill. Pour into small glasses; sprinkle with nutmeg. Makes 6 servings.
