Wait wait wait, milk in before the tea? That's not right.
* If the test involves milk, then it is added to the bowl before pouring the infused tea into it, unless that is contrary to the organisation's normal practice.
* If milk is added after the pouring of tea, the standard notes that best results are obtained when the liquid is between 65 and 80 °C
My organization tends to prefer milk after, But I'm a silly yank who has lots of wrong opinions on a great deal of things (or so I've been told).
I put cream at the bottom of coffee cups before the machine puts coffee in about half the time, though. I have a lot of family in Britain.
