You won't find tiger nuts in Mexico, but you will find horchatas made from many different ingredients, the most common being made from rice and canela, Mexican cinnamon. Some are more watery, while others are creamier from being mixed with milk. Some are made with toasted rice, while others are made with soaked rice, and some are combined with other nuts, grains, or fresh fruits. These mixtures differ from region to region, and each household has their own favorite way to prepare horchatas. Whichever way you make it, a horchata is refreshing and thirst-quenching on a hot day, and is perfect for balancing out spicy and full-flavored Mexican cuisine.
