 Some American supermarkets also carry bottles of "chai spice" alongside their dried herbs and other spices.Unlike Indian spice mixtures, the American ones are generally made from powdered spices (cassia tends to be the dominant flavour) and sometimes sugar; this mixture can be added last minute to an already-brewed cup of tea as straining off the solids is not needed.As an alternative to the hot tea format, several types of cold ""chai"" beverages have become popular in the United States.
