Top tip for anyone at home who wants a fancy cup of tea: add the teabag to your cup of choice, boil your kettle, and, once it’s ready, tilt the cup and pour the water delicately from top to bottom. Then do the same with the milk. Don’t expect a pattern though. Froth the milk beforehand if you want to be really fancy.
