Heat oil in a pan on medium heat. Once the oil is hot, add cumin seeds,curry leaves and ginger.
Now add the yogurt mixture and keep stirring the kadhi on medium heat and once it comes to a boil add around 3 cups of water to it.
Lower the flame to medium low and let it cook for 10-15 minutes. Make sure to stir in between.
After 10 minutes, add the sauteed bhindi to the kadhi and also add the salt.
Let the kadhi simmer on medium-low flame for 20-25 minutes till it gets little thick.
To temper, heat ghee on medium heat. Once ghee is hot, add mustard seeds, cumin, curry leaves and whole dried red chilies (broken into pieces).
Saute till the mustard seeds start crackling and the red chilies turn dark brown in color. Transfer the tempering to the kadhi.
Garnish with some coriander leaves and serve hot with steamed rice.
