Dal Fry and Dal Tadka are both popular Indian lentil dishes, but they have some differences in preparation and taste. Dal Fry is made by frying the lentils in ghee and spices, while Dal Tadka is made by tempering the cooked lentils with spices and herbs. Dal Tadka has a smoky flavor due to the use of charcoal, while Dal Fry has a more subtle flavor.
