Instructions:

In an old fashioned glass, combine the rye whiskey (or cognac), simple syrup and both bitters. Fill glass with ice cubes and stir until chilled.

Rinse a chilled rocks glass with Herbsaint or Pernod then discard any excess liquid.

Strain the mixture from the old fashioned glass into the rocks glass filled with fresh ice cubes; garnish with lemon peel if desired.
