13 Jun 2007 - Gin and It 3 parts gin 1 part Italian vermouth. Stir with ice and serve in a cocktail glass or over ice in an Old Fashioned glass.
Thanks everyone. Yes, I understand what gin and it means but it's the word BE in the clue that I don't understand. If it said "what it means to a barman.." I'd understand it
It seems this was the Sunday Telegraph and I'm relieved to see that the clue was typed incorrectly. The word BE was not part of the clue.
