I would make my own on the stove.I love good chai (none of that pre-mix sugerd-up crap). Try this one, it rocks hot or cold, with honey and/or milk or without:
Good Earth Teas - Category - Chai Teas
2 cups water, black tea, cardamom, cinnamon and a couple cloves.
Boil down to 3/4 cup.
Remove spices and tea, add 2 cups of milk and sugar or honey to taste. Bring to soft boil, and pour 2 servings.
It's poor man's chai, but it works in a pinch. No good cold though.
