If you're a Whovian, then you already know that each regenerated Doctor's sonic screwdriver changes as much as his face. That's why these two recipes for Sonic Screwdriver cocktails are so different –one is based on number 10 and includes blue Curacao, blueberry vodka, Sprite and rum, while the other is based on number 11 and replaces the vodka from the previous concoction with Midori. While I tend to be a pretty big fan of David Tennant's Doctor, something tells me I'd like Matt Smith's cocktail better.
