I've seen a number of posts about how to make chai, so I thought some might like to have the following recipe from an Indian cookbook I have. It is delicious, but note that it only makes about 2 (small) cups. Scale it up for more:
1-1/2 cups water
Put 1-1/2 cups water in saucepan. Add the cinnamon, cardomom, and cloves and bring to a boil. Cover, turn heat to low and simmer for 10 minutes. Add the milk and sugar and bring to a simmer again. Throw in the tea leaves, cover, and turn ff the heat. After 2 minutes, strain the tea into two cups and serve immediately.
From Madhur Jaffrey's Indian Cooking, Barron's, New York, p. 196 (1983).
Hope you enjoy it!
