Firstly, brand of tea will have a significant impact on both strength and flavour. The best teabags are aromatic, by which I mean that when you waft a teabag before your nose you should be able to smell it (this is actually one of my all time favourite scents), and without straining for the scent. If you can't smell the teabag at all then chances are that your cup of tea will be tasteless, little more than boiled water with a trickle of milk. If flavour is the key for you, then you can't afford to stint yourself. My favourite brand of tea is Fairtrade, not cheap by any means, but the main everyday luxury I allow myself. The scent meets the requirements above.
Tea is best made in a teapot, rather than a cup. In my opinion, a teapot must have personality, whether due to the design, pattern, or accessories (i.e. tea cosy). My teapot only has capacity for one cup of tea, but it is duck egg blue (blue is my favourite colour). I also own a bigger, square teapot to match the square teacups Spud and I bought from a car boot sale: definitely unique! A teapot doesn't need to be unique or pretty in order to make a good cup of tea, but it does effect the presentation - likewise, the mugs or teacups.
When the tea has been made, it should be left for five minutes, with the tea cosy in place. If the tea is still weak when it's ready to be poured, stir the pot with a teaspoon as required. Always add the tea to the milk rather than vice-versa. I don't know why but it always tastes better this way. Don't let it get too cold before drinking, but start the sipping process shortly after pouring. Tea is always good with cake or biscuits. Happy tea drinking! How do you like your tea?
