You are too kind, thank you. Dolin makes a lovely dry and blanc. Cointreau, I find, is the most essential mixer to me.
The Smoke and Chartreuse was originally made with Laphroaig 10, so I'm sure it will be fine. The only expression I stock is the 18, hence its inclusion. I, too, love scotch cocktails, but good ones are very few and far between. I've had the Blood and Sand on a number of occassions, and have never found it effective (I find orange juice cocktails in general to be a little flat), so I have always read with interest your stories of Le Lion. Absent the OJ, however, I don't really think it is a Blood and Sand. Interested to hear what you find out. Do you think they might have ginger syrup? My favorite scotch cocktail at present is the superlative Pennicillin from Milk & Honey in NYC -- Ginger-Honey syrup, Lemon, Scotch, with a float of something smoky. Everything that a cocktail is supposed to be.
I know I'm not anywhere near as experienced in cocktails as you, and I know you are not a fan of the place but I found the Blood and Sand at Alembic to be exceptional.
