What furui means
A furui is a small mesh sieve, often paired with a wooden stick or spatula, used to push matcha through fine screen and remove clumps that form during storage. Sifting before whisking is one of the most consistent quality habits recommended by Ippodo and Marukyu Koyamaen because clumped powder will not fully hydrate, leaving grit and dull color in the bowl.
