Steps
Slice the eggplant into thick rounds and sprinkle with a little salt. Set aside for 10 minutes, then pat dry.
Grind the mustard seeds with green chili and a tablespoon of water to make a smooth paste.
Heat mustard oil in a pan over medium heat. Add the mustard-chili paste and sauté for 1 minute.
Stir in turmeric powder, red chili powder, salt, and sugar. Mix well.
Add the eggplant slices and coat them fully in the spice paste.
Pour in yogurt and water, cover, and cook for 8-10 minutes until the eggplant is soft and sauce thickens.
Garnish with fresh coriander leaves and serve hot with rice.
