How to Make It
Rinse a chilled rocks glass with the absinthe, then pour it out. In a pint glass, muddle the sugar cube with the Angostura and Peychaud's bitters. Add ice and the rye and stir well to chill the drink and dissolve the sugar. Strain into the prepared rocks glass. Pinch the lemon twist over the drink, rub it around the rim and discard.
