Since my wife loves chai lattes from Starbucks, we decided to try our hand
at making our own chai mix. Found a good recipe in a coffee-table book we
have. The mix seems pretty good, but I'm skeptical about the brewing method
the book says to use.

It says to mix equal parts water and milk in a saucepan and bring to a boil,
then steep the tea mixture in the milk/water. Doesn't heating the milk in
this way scorch it? And isn't there some chemical process that happens with
the milk and tea (something about polyphenols and milk solids) that might
interfere with the infusion?

Thanks for any hints about brewing the chai.
