Made/tasted this for the first time yesterday.
It's an incredibly time consuming process involving cooking, pulverizing, and straining large amounts of almonds, lime zest, cinnamon sticks and rice, but it's worth it. The spiced almond/rice milk is blended with simple syrup and a bit of heavy cream and served over ice. Absolutely delicious, especially in warm weather. Next time you're in a Mexican restaurant, definitely order a glass.
