Steamed rice with herbs (or, actually, herbs with rice)

This Iranian rice, called sabzi polo, is normally served with fish but works well with almost anything else and also on its own with just a condiment.

The method I describe is very particular but it is essential you stick to it to get incredibly light and fluffy steamed rice. Ther
