OK, if you're going to be a tea snob you just have to use loose leaves in a pot. The pot lid is important: it has to have a hole in it to let the steam escape and a lip so that it doesn't fall off when you're trying to pour the tea. There also needs to be a filter at the base of the spout to ensure that the tea leaves don't come out into your cup.That was easy but I was hoping to work my way up to tea snob.
The amount of tea you use depends on the size of the pot - aim for about three teaspoons per pint. Allow to brew for a few minutes - test by pouring some and checking the colour. Turn the pot clockwise three times during the brewing period to ensure that the infusion is spread all the way through the pot.
Whether you go through the whole tea ceremony or just dunk a tea bag in a mug its the flavour of the water which is going to make or break your brew. You may want to use filtered water if your tap water is very metallic.
Then there's the question of the milk - do you put it in the cup first then add tea or vice versa. Personally, I add it last and adjust the quantity depending on the strength of the brew.
Frankly, coffee is safer - a really good cup of tea is hard to come by.
