Chill a lowball (whiskey) glass in the freezer. Rinse with absinthe, discarding any remaining absinthe; fill with ice. In a stainless shaker, muddle the sugar and bitters (or simply mix if using simple syrup). Add the Seven Jars Preamble Rye Whiskey, and strain into the lowball glass, pouring over the ice. Twist the lemon peal over the top of the drink, do not stir! Garnish with the lemon peel or discard as desired.
