DIY Gingerale. Or, if you're like me, double the amount of ginger, and make it DIY gingerbeer.

Seriously, you may not be into brewing, but this is ridiculously easy. There's nothing in here that you can't get at the supermarket. Just mix all the ingredients and wait 24-48 hours. For my next batch, I'm thinking about going with lime instead of lemon juice, for use in Moscows Mule.
