yes, i love cooking or making desserts with green tea (matcha tea powder). however, i use lower grade not for drinking like the cheaper kind food grade. i have made the japanese chiffon cake, it is like a cake with a hole in the middle... angel food cake mold? anyways, you can also put in green tea leaves but i prefer using powder. sometimes i top it with cream and sprinkle the powder.http://matchagirlparis.blogspot.fr/2013 ... majyu.html
i only use for dessert, i tried were various types of cake like matcha castella cakes etc and also nice to make matcha pudding! if you have a ice cream maker you can make matcha ice cream!
in japan they sprinkle matcha on top of rice and it exists matcha salt to sprinkle on food!
