I was raised with George Orwell's treatise "A Nice Cup of Tea" (Evening Standard, 12 January 1946) firmly memorized, although my family has tended to go him one better on his last two points. He maintains that the milk should be poured into the tea, not the other way around, but that no true tea lover should take sugar. In our family we have always maintained that milk or lemon in tea is every bit as scandalous as sugar. If you like tea, drink tea. If you want lemon and milk, have them instead.
I cannot understand, though, why Americans (and I don't necessarily count myself among them, having been raised by people who aren't from here) don't understand tea. They are haphazard in its preparation and uneducated in its consumption. On the other hand, they are willing to spend astronomical amounts not only on actual coffee beans, but on equipment with which to brew them, etc. I actually read about a guy who modified his espresso machine with the sort of temperature stabilizer used in semiconductor manufacture.
