If you can find the big bag green tea powder in an Asian grocery, it costs very little for half a pound – unfortunately I can’t never finish a bag no matter how frequently I use it :-p
But it’s only fine green tea powder, not matcha grade. But when mixed with milk, the difference between the two is insignificant.
