What’s the difference? Mexican horchata is made of mostly rice. Salvadoran horchata is made of Morro Seed. The ingredients in most Salvadoran horchata bags will read something like: Morro Seed, Rice, Cocoa, Cinnamon, Peanuts, Sesame Seed, Vanilla, Milk and Sugar. I wish there was some way to let you smell it. If they made Salvadoran Horchata perfume, I would wear it… and then lick myself. Seriously.
