Step 1

To a large pitcher or carafe, add the water, rich simple syrup (recipe below), rye whiskey, Peychaud's bitters, and absinthe. Shake or stir to combine. Place in the freezer to chill for at least two hours. It can be stored here indefinitely.

Step 2

Once ready to serve, simply pour the mixture into chilled rocks glasses. Optionally, garnish with a lemon peel before enjoying.

Step 3

Add the ingredients to a saucepan and stir once to combine. Bring to a boil and let simmer until the sugar is dissolved, without stirring. Turn off the heat and let cool before transferring to a bottle or lidded container for storage.
