Agree with the others saying swap the lemon and frangelico, may even kick the lemon down a smidge more next time. Sesame oil and frangelico are a match made in heaven, makes me want to add a little sesame oil to some other frangelico based drinks.
My wife and I had done a side by side for a few different gin-vermouth-Benedictine cocktails and for our tastes we found the higher the gin ratio the happier we were (The London Gypsy with no vermouth won out) but they all also had a larger ratio of Benedictine than this one. I blame it on our martini bias getting drier year by year.
Fanatastic, I ended up doubling the vodka but it was good as is. Sweet, but that's part of the point. Similar flavor to a mudslide but not so thick and cloying.
