Pour whiskey, apple cider, maple syrup, lemon juice, and bitters into a shaker.
Dry shake for 10-15 seconds
Add ice and shake it for 15-30 seconds until the shaker is frosty.
Strain into a chilled coupe or Nick and Nora glass.
Garnish with an extra dash of bitters or a thin apple slice (try an easy apple fan like I did)
