Here are some of the ways by which you can easily identify the pure saffron:
If you put a saffron thread/strand in your mouth and if it tastes sweet…. It’s FAKE
Another very very distinct way of identifying is the aroma. But what about the aroma? One should know the aroma to decide whether its right or not.
Pure saffron aroma is very interesting. If u know what Honey smells like, and you also know what hay smells like…you would know what Real Saffron Aroma is. It is literally a blend of Hay and Honey smells.
Put Saffron in water. In some time, it will color the water. But what’s the big deal, so can the fake one. However, when you take the thread out of the water, it wouldn’t have lost its original color, whereas if it is fake, it would completely lose its added color, and wouldn’t look the same.
A very interesting test is to add a little baking soda in water and mix it. Then add saffron to the mixture. The water/baking soda mix shall turn yellow if its Pure Saffron
The fake one will turn dim red.
One of the most interesting Mantras for saffron is to use the word Sweet correctly.
Good saffron should always Smell Sweet and never Taste Sweet.
