You do not put milk in Earl Grey tea. Not ever.
Outrageous. Unacceptable. Do these ignorant barbarians on the Internet not know what a dad-blasted bergamot is?
No. Most of them do not and would not even if one landed on their head with a label pinned to it, reading, "Behold, the bergamot."
I lay the blame for this outrage directly at the feet of the decline of Great Britain. They have Let Their Side Down and now English-speaking tea drinkers outside that island-bound nation are pouring milk into Earl Grey and drinking it (actually drinking it!), thinking, "Yes. Yes, this is how tea should taste."
Ugh. If the Brits were capable of making an acceptable cup of coffee, the asymmetry would be unbearable. Thankfully, they cannot -- for whatever happens, we have got the Chemex, and they have naught.*
Now, if we just had a nice plate of arrowroot digestives.
* "Whatever happens, we have got/The Maxim gun, and they have not" --Hilaire Beloc; sadly, he also wrote, "Is there no Latin word for Tea? Upon my soul, if I had known that I would have left the vulgar stuff alone." He was by birth French and never fully gave it up, just as one might expect.
