For a perfect pot of tea Use fresh water. Water left in the kettle loses vitality and makes tea taste dull. Rinse the pot with boiling water to bring out the tea's flavour. Add 3–4 teaspoons of tea to a 6-cup pot, pour in boiling water and leave to brew for 3–4 minutes, pour through a strainer, add milk or lemon. Whether you add milk before or after is open to debate.
