Preparation: Begin by heating the ghee in a pan over medium heat. Once melted, add the whole wheat flour and roast it gently, stirring continuously to avoid burning. It should take around 8 to 10 minutes to roast the flour until it gets golden brown and begins to smell nutty. Next, add the chopped nuts and cardamom powder to the pan, mixing them thoroughly with the flour. Continue roasting for an additional 2 minutes, ensuring that the nuts are well incorporated and the mixture is aromatic.
