First, pour some of the hot tea into the cup to check its colour. It must be somewhat dark. Then pour the tea back into the teapot. This will do two things:

  1. It will warm up the cup.
  2. It moves the tea inside the teapot around so that colour of the tea is even.

If the colour is light, let it steep for a little longer.

Then fill up one third to half of the cup with tea and pour hot water over it all the way to the top.

And there it is!

Your perfect cup of Persian tea!
