I am posting this here rather than in reply to Pepper further down because it is too damn important to get lost in an old thread.
Pepper, sir you are a scoundrel to suggest such an abomination. Bitters mixed with the gin and poured martini style. I have never in all my many years heard such balderdash. A good gin benefits from La Crima Christi ( as a bartender I know calls the film made by the viscosity of the bitters which cling to the side of the glass).
You will be suggesting next that you should serve it straight up at which point I will have to ask you to step outside and blows will be exchanged.
I am assuming you are not of these shores and am going to warn our kind and friendly people at Immigration to keep a beady eye out for you.
You have been warned.
