I had horchata for the first time a month ago when I visited the Bunnies for Thanksgiving. It was the perfect complement to the fish tacos at Palomino and overall a refreshing and light drink. This version is not quite the same as Palomino's but it is quite tasty all the same, and very easy to throw together.
1 1/3 cup long grain white rice (uncooked)
2 cinnamon sticks
2 cups water
Combine above in blender and blend until coarsely ground (1-2 minutes).
Add another 2 cups of water and blend again. Leave in fridge overnight.
The next day, strain into a pitcher and add:
1 cup water
1 cup milk
heaping 1/3 cup sugar
Shake it up and enjoy!
