It's odd, rice, water, and cinnamon are tasty enough, but when they're put together to make horchata turns into something nasty.
Roger that.
Curiosity got the better of me one day in Wallyworld and I couldn't resist the $.02 on clearance package of Horchata. Got it home, mixed it up per the Spanglish instructions, took a sip, and promptly gagged.
It's a little like drinking a liquefied scented candle - only less tasty.
