Rembrandt's "Boaz Casting Barley into Ruth's Veil," c. 1645
The word "horchata" derives from the Latin word hordeum which means "barley." At one time, barley was the world’s most prestige grain; the further back you go in history, the more important it was. Barley bread was eaten by Plato and Aristotle in ancient Greece and was the bread of the Bible. It would also have been familiar to Confucius in 500BC. The original horchata was the most venerable of grain drinks: barley water. Over time indigenous chufa (also known as tigernut) was substituted for the barley in Egypt.The drink made its way to Spain. When the Spaniards brought the drink to Mexico, the natives used locally grown rice to make the drink. Horchata is sometimes made with melon or squash seeds as well. The rice, nuts or seeds are ground and mixed with water to make a milky-looking agua de fresca.
Horchata is quite well-suited for extinguishing the occasional fires that are ignited by fiery Mexican food. It is especially complimentary to all types of savory dishes including a local favorite of fresh, hot tacos cloaked in spicy pineapple salsa.
1 cup long grain white rice, rinsed
4 cups water
2 cinnamon sticks
1/3 cup sugar (or more to taste)
1 1/4 tsp. pure vanilla extract
1/4 tsp. ground cinnamon, plus more for garnish
Wash and drain rice. Combine rice with cinnamon sticks in water and soak overnight in the refrigerator.
After the rice has soaked for a minimum of 8 hours, preferably overnight, discard the cinnamon sticks and pour rice, half of the soaking water, sugar and vanilla into a blender while reserving the unused soaking water. Blend rice on low for 3-5 minutes until well blended and finely ground. Pour the blended rice mixture through fine mesh sieve two times, and then through cheesecloth one more time to remove all gritty bits of rice.
Pour the strained rice water mixture into a pitcher adding the reserved soaking water and stir well to combine. Add more sugar if needed, to taste. To serve, pour over ice and garnish with ground cinnamon and a lime wedge, if desired.
