I used the Catoctin Creek Roundstone Rye 80 Proof.  It's a very nice sipper and honestly goes awesome as well in cocktails.  Sip it and you'll have some notes of banana, toffee, chocolate, white pepper, vanilla.  Make a cocktail and you'll have endless options!  So here's my option!

2 oz Catoctin Creek Roundstone Rye 80 Proof
¾ oz lemon juice
½ oz white pepper syrup*
¼ oz Giffard banana liqueur
1 egg white
Couple dashes angostura chocolate bitters and angostura aromatic bitters
Shaved chocolate garnish

Place all the ingredients in a shaker.  Wet shake, dry shake, or vice versa, whatever you prefer.  Then, strain into a chilled coupe, and garnish.

*White Pepper Syrup

1 cup spring water
½ cup sugar
1 bar-spoon ground white pepper
1 bar-spoon vanilla extract
1 Tbsp of rye
½ Tbsp of lemon zest

In a sauce pan, place sugar, water, pepper, and vanilla.  Heat on medium-high and stir until dissolved (7-10 min).  Bring down to medium-low and add rye and lemon zest.  Let simmer for 4 minutes.
