No-one drinks more tea than the Northern Irish, therefore my opinion on the matter to hand supersedes all others.
Boil kettle
Add 2 tea bags to a tea pot (Nambarrie brand)
Add boiling water and simmer on a low heat for 5 minutes
Pour “stewed” tea from teapot to cups/mugs
Add milk and sugar (if desired)
Serve tea to everyone in the household, including all visitors. If you have visitors you must serve tea within 5 minutes of their arrival.
Repeat entire process in about 1 hours time or if other people arrive.
Serve with biscuits suitable for dunking such as rich tea, digestives, ginger nuts etc.
