I stumbled upon this video of bartender Jim Meehan walking us through each step in making the perfect martini and loved it.
You've probably seen other "how to's" like this - there are many - but I like this one because I think he gets the proportions right and there is a good lesson in the old "shaken vs stirred" debate (hint: he stirs).
Have a look:
Thirsty now? Yeah, me too.
