1 1/2 ounces vanilla-flavored vodka
1 ounce lingonberry concentrate (recommended: Hafi) see Cook's note,
1 to 2 dashes bitters
Juice of 1/2 orange
Juice of 1/2 grapefruit
1/4 wheel fresh grapefruit or orange, or a twist of each
Cook's Note: Look for lingonberry concentrate at specialty stores, or stores that feature Scandinavian products. If unavailable, a good substitute is 1 ounce cranberry concentrate plus 1 teaspoon sugar.
