Prepare blueberry layer following one of these options:
A- If using blueberry jam:Mix the blueberry jam with the milk. You may do this directly in the cup, using a spoon or a handheld frother (this second option makes it quicker and easier).
B- If using fresh or frozen blueberries:Microwave them with sweetener of choice and 1 Tablespoon water until tender (it takes around 30 seconds). Then mash with a spoon and if desired, strain.Add milk (warm of cold, depending on what you prefer).
Prepare a matcha shot by whisking or shaking the matcha powder with a little amount of water.
When the matcha is evenly distributed and has some build a fine layer of foam, add it into the blueberry milk.
Notes
Feel free to increase the amount of jam or sweetener to taste.
If you want your drink to have two layers (pastel purple and green), assemble following this steps: blueberry latte - ice cubes - matcha tea (aiming at an ice cube helps).
For three layers (intense purple - white - green), assemble: blueberry jam or microwaved “syrup” - ice cubes - milk - matcha concentrate.
You may prepare this drink hot or iced: both taste great. To make it warm, heat the milk. Just take into consideration that layering doesn’t work when the latte is warm.
