 The method may vary according to taste or local custom; for example, some households may combine all of the ingredients at the start, bring the mixture to a boil, then immediately strain and serve; others may leave the mixture simmering for a longer time, or begin by bringing the tea leaves to a boil and only add the spices toward the end (or vice versa).A common Maharashtrian practice for preparation of one cup of chai is to first combine one half cup of water with one-half cup of milk in a pot over heat.Sugar may be added at this point or after.
