Place one teaspoon per cup into an infuser, filter or teapot. Switch the kettle off, before it boils, when you hear the water rumbling. Add the hot, but not boiling, water and infuse for 3 minutes. Serve immediately or remove leaves to prevent spoiling.
Gyokuro Asahi is the rarest Japanese tea of all, being grown under special bamboo shades to give a tea with a uniquely fragrant flavour. The fine emerald needle-shaped leaves give a bright, aromatic exquisite infusion.
