Ideally you'd have a mortar and pestle to crush the ginger and cardamom seeds, as well as a strainer. Quantities of most ingredients are to taste.
Cleansing Chai Tea
3 sticks of cinnamon
3 whole cloves
cardamom seeds, broken open
Add spices to water in a saucepan and slow-boil for twenty minutes or more. If you're going to add milk afterwards, let the tea come to a boil two or three times before straining so that the flavor holds up against the milk. Pour mixture through strainer into teacups and add honey to sweeten.
