Why can't it be serious? Sounds perfectly normal.
Perhaps it's trying to make the point that a simple cup of tea involves all sorts of resources from around the world.
That aside, for a one-cup brew using a teabag, my recipe would be:
1. Boil a kettle of filtered water.
2. Put about an inch of the hot water in your cup, swirl it around and leave for a few moments, while you open a packet of Brooke Bond Choicest Blend tea bags and sniff it, savouring the heavenly aroma. (Yorkshire Gold or Twinings Assam Orange Pekoe are good substitutes).
3. Pour the water from the cup, add the teabag, reboil the kettle and immediately pour the hot water over the bag, AS SOON as the kettle's switched off.
4. Add a splash of semi-skimmed milk, then leave for at least 2 minutes.
5. Use a teaspoon to squeeze the bag against the inside of the cup, then remove it.
6. Add sugar as required, stir, settle down on the couch with your tea and a plate of Fox's Vienna Sandwich biscuits, and enjoy your treat.
