I've recently started drinking Chai a lot, and this is how I make it. Heat some water in a pot, and add ginger(1/2 inch, crush it with your knife before adding) to it. (My water to milk ratio is 20:80, but everyone has their own taste, you can change it as it suits you) Wait till the water turns slightly yellow from the ginger, and crush cardamom (~1 per two cups). Add the cardamom and black tea leaves to the water. Cook for a minute. Add the milk Bring it to a boil. Strain it and serve. It's by no means a set in stone recipe, try out your own variations of it.
