In a relatively small bowl, add 1 tsp of matcha powder.
Next, pour in 1 tbsp plant milk/water (the liquid should be around 180 F or 80 C).
Whisk until all the lumps are dissolved. You could use a spoon, it's gonna be even easier.
Add 1 more tbsp of liquid and mix until combined. Be patient! Repeat the procedure 2 more times.
Pour in the matcha into the milk/water (the liquid should be at least warm, afterward you can add ice to cool it).
Whisk with a milk frother or a spoon.
