Follow the Martini Rules
Martini purists have spent quite a bit a time over the last year lambasting the Vodka Martini saying it's unpure and takes a way from a true Martini. Cleveland.com (Yes, Cleveland) has an article about The Proper Martini Rules that brings the Martini back to its roots of a fine Gin and Vermouth (Originally, more Vermouth than Gin).
It finally puts in print what a lot of us have known all along. Shaking a Gin Martini doesn't "bruise" it, but it does make it cloudy, which is a no-no. So, make sure you stir your gin libation.
Oh, and make sure you hold your glass by the stem. We don't want your greasy mitts warming the thing up.
