We loooove horchata, my husband in particular. If you've never had it, here's an article with more info. Basically, the horchata we are used to is sweetened rice milk with vanilla and cinnamon. It has a rather unique flavor and is very good! There are recipes out there to make it completely from scratch and I fully intend to give it a try sometime soon, but this "cheater's" horchata made with packaged vanilla rice milk is good, too! I suggest you make it several hours ahead of time (or even the day before) so the sugar has time to dissolve and the cinnamon has time to soften and disperse through the milk. The cinnamon will never blend in completely, but it will still be good!
1/2 gallon vanilla flavored rice milk
1/3 C sugar
1 t cinnamon
Place everything in a pitcher and stir to combine. Refrigerate for several hours and stir again before serving.
