Use about equal parts spices and tea.
For 2 cups:
1 heaping teaspoon black tea leaves (or a teabag. PG Tips is my favorite kind of bagged tea)
1 heaping teaspoon ground spices:
~3 cardamom pods
1/4 stick cinnamon (or a big pinch of the ground stuff)
Big pinch whole cloves (don't use the pre-ground ones, they taste like nothing)
Small pinch peppercorns
Big pinch grated fresh ginger (if making to consume immediately) or the dry stuff (if making to save for a bit)
To brew, heat water to just below boiling and brew in teapot or cup for 4-5 minutes. The tea will sink to the bottom of the cup or pot into a mucilaginous goo that is very strong-tasting... You can attempt to strain the teapot before decanting into a cup, but it's fairly futile. Just let the grounds settle to the bottom of the cup.
Add a good quantity of warmed milk (cow and soy are the best-- rice milk is too watery for my tastes), and sugar/honey to taste!
