Prepare your warm water using a kettle, the microwave or the stove. You want the water to be warm but not boiling.
Place your sifter over the top of your matcha bowl.
Using a matcha scoop, scoop the matcha powder into the sifter over the bowl. Use the back of the scoop to gently push the matcha powder through the sifter.
Pour the warm water over the top of the sifted matcha.
Use a bamboo whisk to whisk the matcha and warm water together. You want to make back-and-forth motions with your bamboo whisk (an M or W motion). Whisk the matcha and hot water until no clumps remain, and the matcha is nice and frothy.
Steam your milk using a steam wand, or warm the milk using an electric milk frother.
To a coffee mug, add the cranberry syrup, white chocolate sauce, and the steamed milk. Stir to combine and dissolve the sauce.
Pour the whisked matcha over the top, and enjoy!
