I just stumbled upon this video and thought I'd share it with you. It's by Grey Goose and features the Poire Pear Cocktail (yes, that translates as "pear pear"....oh well). If you follow the YouTube link, you'll see that Grey Goose has an entire series of how-to videos. Very handy for creating some memorable cocktails at your next event!
By the way, when he says to add sugar, he probably means superfine sugar, which is essentially the same as regular granulated sugar, but ground into small pieces. It dissolves better than regular sugar (so, not totally necessary, but nice to have). If you can't find some at the store, you can make your own by running regular sugar through a coffee grinder until powdery. Be sure to let the sugar settle for a moment before opening the coffee grinder, or you'll have a big cloud of sugar dust in your kitchen!
