I strongly believe that tea can only properly be made with the leaves of the tea plant, Camellia sinensis.
And that the water should be freshly boiled and poured over loose leaves that have either been fermented (i.e., black) or partially fermented (i.e., oolongs). I do not prefer the unfermented or "green" tea.
I prefer a large mug

and half-n-half and sugar.
