Wtf is Horchata, btw?
LET ME GOOGLE THAT FOR YOU.
Just kidding, I'm too lazy.
It's like.... Rice milk, or almond milk or something with some cinnamon or something. I dunno. It's somewhere between water and cow's milk, and goes great with tacos.
There's a Mexican restaurant and Mexican taco truck I go to that serves some killer horchata. Really makes the meal.
I've also seen it in the soda fountains at the 7 Eleven in my town, but you should stay away from that stuff. I don't think it's really horchata, more like the sugar water with other flavors similar to soda.
So in conclusion, good horchata is good, bad horchata is bad.
