Hmm, I see a 2-star review means "fair". I guess that's what I'll give this. I made it exactly as written - several times actually, since I had some cognac to use up. It was okay, but didn't especially strike my fancy. Maybe others who like cognac more than I do will love it, though.
I made this highball exactly as written. It's a very nice drink. Thankyou for posting.
