Much more lemony than I expected. Fixed with 2:1 simple syrup and it was very refreshing. I'm more of a Manhattan kind of guy so this was a real change and delight for me. Will definitely make this for friends that are not so much into whiskeys.
Delicious Classic! Variation: Substitute Cognac with a good Calvados, whose fine an dry apple aromas round up perfect with the Chartreuse.
Left all amounts as in original receipt.
Oh it turns out that instead of simple syrup, I used this herbal chinese medicinal concoction that my girlfriend's mother made for me. It's supposed to be helpful for alleviating a pinch nerve, but it certainly not a good sub for sugar water. Going to try this one again tonight with the right ingredients this time. Cheers!
I recommend expressing and discarding the lemon twist garnish that’s specified here.
