Saffron - An Introduction
There is no doubt that Saffron is an expensive spice. More that 90% of this spice is cultivated in Iran and of course it’s a well-known fact Iranian saffron spice is the best!
The Crocus Sativus flower has 3 threads. When buying saffron you look for 3 grades… Sargol (tip of the thread) Negin (all of the red thread and minimum yellow) and Pushal (all of thread).
Because of its nature it is very easy to adulterate saffron. One of the methods used by some is to lace corn silk with food dye and saffron scent.
