Sazerac

In a glass, add the sugar cube then the bitters. Muddle the sugar cube until mostly dissolved. Add the Cognac, rye whiskey and absinthe and fill the glass with a handful of ice. Stir well until chilled.
Strip a large slice of a lemon peel.Squeeze the lemon peel into the drink to release the oils. Run the peel around the edge of the glass, then place it in the glass. Enjoy!
