Horchata is a traditional Spanish drink made of tiger nuts (they are not actually nuts) that tastes creamier than most nut milks. It's perfect if you have a nut allergy and are dairy-free! Tiger nuts are naturally a bit sweet so you really don't need to add any sweeteners to the recipe. I added a little bit of vanilla and cinnamon here to give it more of a dessert feel. It's full of magnesium and iron too which is an added bonus.
