This dish is simple to make, but it's all about having the right ingredients. I learned to make this during a cooking class in Chiang Mai, Thailand, and have recreated it stateside several times since — with varrying results. This time, I got it right, by searching out the most authentic Thai ingredients. It's possible to substitute in brown sugar and a different kind of rice, but it just won't yield the same results. To get the most out of this delicious dessert, visit a Thai grocery store in your area to make sure you are getting the right products.
