If you've ever made ice cream yourself, you know that if you don't eat it right away, it gets pretty hard in the freezer. Keep ice cream creamy all the time by putting some alcohol in the mix.

OZY has the scoop on the science of great ice cream. David Lebovitz, author of The Perfect Scoop, recommends adding some alcohol to your mix -- it freezes at a lower temperature and is less likely to form crystals.
If you want a neutral flavour, throw in some vodka, otherwise try some Schnapps. Obviously, this makes your ice cream an adult-only treat, but it's an easy way to get that creamier texture.
