Fill Zojirushi water boiler & warmer with water and set temperature to 208°F.
Place black tea leaves into the teapot.
When the water temperature reaches 208°F, dispense 24 fl. oz. of the hot water into the teapot. (If using a tea kettle to boil the water, pour hot water directly into the teapot.) Allow the tea to brew for 4 minutes.
Pour fresh cold milk into the cup, if preferred.
Pour tea into each teacup alternately so that the strength of the taste is equal for every cup. Serve with sugar.
