Super delicious! But even at just 10ml the Chartreuse was the most forward flavor so i think I'll tone it down to 7.5ml next time and i think it'll be perfect balance for me.
I've made this three times and now want to try the original with 1/2oz Green Chartreuse, 1 & 1/2oz Cognac and 3/4oz sweetened lemon juice. The only question is finding the right amount of lemon juice to simple syrup. 1/2oz lemon juice to 1/4oz s/S, or 2/3oz lemon to around a bar spoon s/S?
