I also made mochi ice cream to celebrate the release of Legend of Korra Book 2. And it turned out very well.
We inadvertently discovered the perfect ice cream for mochi. BYU catering makes this weird lemonade-like drink called "Y Sparkle." In the same odd tradition, the creamery has sparkle sherbet. It's tangy and intense, and when you get to about the third lick it reaches out and whips itself around your tongue and squeezes like a python. In a good way. And I'm not actually kidding at all. That's what it feels like.
I've also finally found a good recipe for mochi. Check out these two links. The first is for the converted measurements, and the second is for the actual recipe.
Making mochi ice cream was much easier than I thought, and it's a satisfying process involving gooey sticky dough.
And of course, you can use any ice cream you like. (But really, trust me on the sparkle sherbet.) The other ingredients are mostly easy to come by. They sell sweet rice flour/powder in most speciality food stores AND usually in the Asian section of your local grocery store. I found it at Macey's the other day. I don't remember it being particularly expensive, and one box is enough to make mochi forever. Almost. Look for a box like this.
It is the perfect treat for celebrating today's Legend of Korra episode. Flameo, Hotman. Flameo.
