Now add gram flour/ besan to the Kadai slowly with the help of a steel or wooden spatula. Slowly roast this on the medium flame. Keep stirring and feel the aroma. Once you get the roasted aroma of gram flour, check it with spreading one tablespoon of water on it (I call this water test). If water evaporates immediately leaving yellow bubbles on top, it means your Besan is fully roasted. Switch off the flame and keep stirring for few more minutes as heavy bottom pan takes time to cool down and we don’t want our Besan to get burnt smell. The whole process of roasting takes about 10-12 minutes.
