I don't drink them. In fact, I have a severe aversion to most "white" spirits ... a result of youthful indiscretions. No gin for me, and definitely no vodka or rum!
But my wife loves a martini now and then, and I would like to know how to make a great one for her. She describes her favorite as being so cold that there is a thin slurry (my word, not hers) of ice floating on the top of the drink. She says she likes both vodka and gin martinis.
Any recipes, including techniques, that might yield a platonic ideal?
