500 ml (2 cups, roughly) water
1 cardamom, in its pod
4 cm knob of ginger, sliced thinly
4 black peppercorns
1/2 cinnamon stick
1 lime, juiced
1 TB of your favourite tea (or 2 tea bags; ugh, tea bags)
Over highest heat, steep the clove, cardamom, sliced ginger, black pepper, cinnamon, and the juice of the lime (along with the leftover lime halves, if you're feeling adventurous) in rapidly boiling water for three minutes. Turn off the heat. Add your tea leaves. Allow it to steep for four minutes, with the heat off. Serve your tea piping hot. Strain out all the bits and bobs, and refresh it by pouring another 500 ml of boiling water over top the whole mess, and steeping it for five minutes. Strain again, and use the stuff for a third steeping.
If you're using tea bags, you need to steep the tea for four - six minutes, and only use it once. With actual tea, however, you can generally get three good steepings out of it, at the very least. In fact, the second and third steeping tastes better than the first one, which is why I suggest a relatively quick steep for the first go-around.
I and Steve both prefer this without sweetener, because it's so flavourful without. All the spices give a bit of sweetness on their own, without needing to rely on sugar. I urge you to try it on its own, and see if you can take a strongly flavoured tea, all on its own. You'll surprise yourself, as you reach for this blend for your morning cup of tea, and cut back drastically on the amount of sugar you pour on.
