Horchata is a Mexican rice drink with condensed milk, cinnamon and vanilla. There are many ways to make horchata, but for me this recipe is the perfect one. Served over ice, this will be a refreshing hit this summer! The preparation requires a little patience, but is not difficult at all. I would recommended adding the sugar slowly at the end so it doesn't become too sweet. A guideline is two tablespoons, but depending on your taste it can be more or less. The drink will keep for a few days in the refrigerator.
