Horchata is a drink that is made differently depending on what country you're from or happen to be in, and often depending on whose house or restaurant you happen to be sitting in at the time. It can be made from almonds, cashews, tigernuts, sesame seeds, rice, and even, rarely, barley. In my home, it's made from rice, cinnamon, water, a bit of vanilla, and some milk, though sometimes cream, if I want it to be rich. You can follow exact measurements, or you can mix to taste each time you make it. My favorite part about horchata, besides of course the fact that mine tastes like drinkable rice pudding, is that it's ridiculously easy to make, as long as you have a blender, and you think ahead.
