I've never had a vodka martini and probably never will. I like Bombay Sapphire the best or any London dry gin. I've have Tanquery martinis but I'm not that fond of them. I was desperate one night and used some Fleischmans's gin and it was so horrible, I couldn't finish it.
Just a touch of vermouth, shaken, poured into a martini glass (that I keep in the freezer) and I like either onion or bleu cheese stuffed olives.
I like the idea of keeping the gin in the freezer but I've never done that. I should try that.
