To make a good cup of tea - leave the teabag in boiling hot water for 5 minutes, then strain against the side of the mug with the back of a teaspoon (critical step). Due to the loss of temperature, put the mug of black tea into the microwave for 30 seconds. Only after doing this apply milk, semi skimmed or full fat only (unless your name is Ed). Substitute milk is a big NO NO.
The lack of this knowledge these days is frankly alarming.
You’re welcome.
