I have become completely addicted to Matcha Green Tea. If you are not familiar with Matcha, here is a link to a rather lengthy but fascinating description. It is from the seller I buy my matcha from. http://www.recipezaar.com/cookbook.php?bookid=125553 You can order Matcha by googling for sites, keyword "Matcha" or looking in the Japanese section of your grocery store. My personal favorite is Shizuoka, but you can use any quality Matcha Powder you like. I think you get better results with an Ice Cream maker, but alternative directions are given. Cooking time is dependent on your ice cream maker, or process used.
