I may be showing my inner gringo here, but I don’t really “get” horchata.
I mean, I love Mexican food, and while I do find horchata to be pretty yummy, I’m not sure what it’s supposed to be. Is it a dessert drink? Like do you order it as a treat after you finish your tacos? Or are you supposed to drink it along with your main meal, as you would with water or soda? Or is it something you just drink whenever, regardless of context or time of day? I don’t know.
