Pulverize tea leaves in a blender or similar. In order to pulverize them evenly, pulse for 3 seconds, shake the blender, rest, and repeat several times.
If the powder seems too coarse after blending, or if you don't have a blender, grind it up in a grinding bowl with a pestle. Sift the powder, and keep grinding up any coarse bits to make a fine powder.

Story Behind this Recipe
Matcha is expensive, plus I only had a little when I wanted to make green tea cookies. So I tried making the powder from tea leaves.
Choose tea leaves that are as green as possible, and grind into as fine a powder as possible.
