Start by placing a teaspoon of matcha powder into your bowl or cup.
Pour hot water over the matcha, just enough to cover it, and then whisk vigorously in a zigzag motion until the powder is fully dissolved and the mixture becomes smooth and slightly frothy, with no lumps remaining.
Set a fine mesh strainer over your glass and pour the whisked matcha through it to catch any remaining clumps, ensuring a silky-smooth liquid.
Add your preferred sweetener, such as simple syrup or honey, and stir gently to combine.
Fill the glass with a handful of ice cubes, creating a chilly bed for your drink.
Pour cold milk over the ice and strained matcha mixture, filling the glass to the brim, and watch the vibrant green contrast with the creamy white.
Gently stir the beverage to combine the layers, creating a smooth, velvety texture with a faint froth on top.
Serve immediately with a straw or a spoon, and enjoy the refreshing, grassy aroma and crisp, icy sip.
