Heat water to 80C (an electric kettle lets you be precise), using a little more than required because we will need some to warm the teapot.
Pour a little water into the teapot and swirl it around. Discard this water.
Put the tea in the teapot and pour the water over it. Cover the teapot and let steep for 3 minutes.
Strain the tea (if not using a bag) and pour into a cup.
Notes
Why warm up the teapot before pouring the water?All the pros do it so that the water temperature doesn’t drop drastically when you brew the tea.StorageKeep in the fridge for up to 4 days.
