Put ghee into large non-stick pan. And melt it on slow flame. When ghee is slightly hot add wheat flour.
Stir with spatula, the mixture looks like thick paste and feels heavy while you are stirring it.
Now roast the flour into ghee, if ghee is not enough to roast the flour, you can add more. First add 1 tbsp, then if you still required then add one tbsp one by one.
Stir it continually on medium heat for 4-5 minutes, then slow the flame and keep starring.
Now turn off the gas.
