1 oz cognac

1 oz bourbon

1/2 oz Green Chartreuse

1/2 oz vanilla syrup

1/2 oz lemon juice (I used 3/4 oz because when I testing before shaking way too sweet)

Cardamom bitters (I don’t have this but put a shake of cardamom, and wished I had pods instead)

Shake all, pour into chilled coupe.

This is good but I wouldn’t say great. If doing again without the cardamom bitters I would absinthe rinse the glass instead. In fact, I think I would absinthe rinse anyway. And less syrup, though it’s hard to measure smaller than half an ounce.
