Although this spice tea is clearly enjoyed by Tuvok and Captain Janeway (VOY: Alliances), I would also like to think that it is a common drink on all of Vulcan, because it is refreshing, spicy and logical all at the same time. I am a little suprised to see Janeway drink anything other than coffee, but can understand why a coffee drinker would enjoy the strong flavours of this tea.
While I have listed quantities of spices below, the recipe is very flexible - if you want more of any spices, feel free to add it! Remember to steep your spices for a few minutes to allow the flavours to develop. It is a bit difficult to only make the amount of spice needed for a single cup, so I suggest you make the quantities below and store the mix in a jar - pre-made spice tea, whenever you want it! The recipe below does have quite a spicy finish - if you want to lower that a little, use less peppercorns and ground ginger.
