Use only the finest tea. Bring the water to boil. And rinse the tea pot and tea cups with hot water. Pour the boiling water into the pot containing the tea leaves. Keep the lid closed while allowing the tea to brew for 4-5 minutes. To get the best taste over brewing is to be avoided.
Strain the tea out into cups thereafter. Use a "Tea cosy" to keep the pot warm should there be a delay in serving.
The quantity of tea leaves used will vary according to taste. Generally 10g of tea makes 4 cups. Experiment till you get it just right. Adding sugar and warm milk will reduce the effects of over brewing
