I scream, you scream, we all scream for matcha ice cream! Matcha is a finely ground powder made from specially processed green tea leaves that can be found in tasty beverages, sweet pastries, and of course, rich ice cream.
Green colored ink from China. (Does not taste like matcha, it only resembles it in coloration. Please don't taste the ink.)
