1 lemon, juiced
fresh ginger root
a short piece of cinnamon stick
echinacea (loose or in tea bags)
maple syrup or agave nectar
Dump a few cups of water into a pot and put it on the stove. As it comes to a boil, add several thin slices of ginger root, the lemon juice and the lemon itself, the segment of cinnamon stick and a healthy dash of cayenne pepper. A friend of mine also adds fresh garlic - I'm not quite so daring.
Let the whole mix simmer a while, then strain it into a tea pot containing the echinacea - I used two organic tea bags. Let it steep until it's nice and strong. Pour a cup, sweeten to taste with maple syrup or agave nectar (or sugar if that's what you have) and drink up!
Best enjoyed with with a lap full of sleeping kittens.
