Adjust the thickness of the frappe by increasing or decreasing the amount of ice according to your tastes. I like thick icy drinks.
Please don't use contents of green tea tea bags, it's a whole different taste than matcha.
You can substitute almond milk, rice milk, or soy milk for the milk. I notice almond milks leaves a distinct after taste.
This recipe is versatile in its ingredient amounts, you can add more ice it you want it thicker, more matcha green tea powder if you want it thicker, or more vanilla syrup if its not sweet enough.
