Do you have 'green tea ice cream' recipe. . How are I get green tea powder?

I have tried buying the japanese gree tea ice cream powder but it has a lot of sugar. Thought of grinding my own green tea but don't think the powder would be fine enough and I assume it would taste too terrible. Haven't tried it. Would this have worked? has anyone tried grinding gree tea leaves? does it work? does anyone have any green tea ice cream recipe? thanks in advance.Do you have 'green tea ice cream' recipe. .
