some tea's take kindly to a bit of milk an sugar... some don't, the main thing is not to steep it too long!! there are different temps and different times for different types of tea ie white tea, green tea, oolong tea, black tea. theey are all the same plant just the first two are dependantupon when it was picked, as they are immediately dried after... however oolong and black tea are both allowed to ferment to a degree, black tea being the longer!! if you steep them for too long it will become more and more bitter!! black tea maxes out at about 9 minutes I think so it's something like 7-9 for best flavor, green tea is only like 5-6 minutes if I recall correctly. if it's a black tea mix you might wanna try a little milk an sugar... otherwise just experiment around a bit till you find what works for ya!! I sometimes like my black tea with a lil cinnamon, milk and sugar... pretty tasty!! anyways hope that helped a bit!!
make a muddle of ingredients in the bottom like you would for a mixed drink such as a mojito, etc. Match the ingredients up to the type of tea it is. For example, in a mango tea, try muddling some mint leaves, a little sugar (acts as an abrasive to help the muddling process), and a tropical fruit of your choice.
Or, chill it in a big pitcher and add pretty slices of fruit, etc, like a sangria.
