Horchata is a rice and cinnamon beverage popular in Latin America. This version is a riff on the style of horchata prevalent in Mexico but assorted recipes come from West Africa and Spain. The Mexican style horchata often employs ground white rice, cinnamon, and almonds. With the addition of tequila and a spicy, acidic lime clementine cordial, this is a delicious drink served either hot or cold.
