It is the definitive answer.
Not really if you follow those steps you end up drinking out of a bowl

It is the definitive answer.
Either the way Guy Martin describes in the video here:
Or according to the British standard BS6008.
That's how i do it. Apparently there is some science to putting the milk in first. If you add milk to the hot water there is way more hot water than milk so the milk instantly gets to boiling temperature and denatures whereas when a slow pour of boiling water is added to a pool of milk the entire milk warms up slower and denatures less. Could be bull though i suppose.
Why has everyone ignored this post? It is the definitive answer. Also available here in a dedicated British Standard: http://sub.spc.org/san/docs/BS6008.pdf
I'm up for the bag out before milk in, but I can't see how it makes a huge difference.
Boil Kettle,
Warm up Teapot with a little boiling water, swish it around a bit then tip it out
Teabag(s) in pot, add water
Give a little stir, leave to brew for a couple of mins
Milk in Cup(s)
Give tea one last stir and squeeze teabags with spoon against the side of pot
Pour tea into cups.
Enjoy
Depends on the tea whether or not I have milk. Also. CBA with loose leaves most of the time, although they are SO much better.
Well the tea bag is going to absorb some of the milk.
