A friend had this drink at a long-forgotten bar in Brooklyn and recreated it. The Fernet and maple go nicely together, and in total it ends up being quite refreshing.
2 oz rye whiskey
⅓ oz Fernet Branca
¼ oz Maple Syrup
¼ oz Maple Liqueur
2 dashes orange bitters
2 dashes Angostura bitters
ginger beer
Shake ingredients (except ginger beer) with ice. Strain into a collins glass, top with ginger beer, and garnish with an orange peel.
