2) Heat oil in a 10-inch skillet (about 1/4 inch deep) and fry aubergine over medium to high heat until golden brown, about 3 to 4 minutes on each side. Remove and let drain on paper towels. Set aside.
3) Heat 1 tablespoon oil in a 4-quart saucepan. When hot, add ginger and garlic and saute for 20 seconds. Add chopped onion and saute over medium heat until soft, about 6 to 8 minutes. Add paprika, 1 teaspoon salt and tomatoes; simmer for 30 to 40 minutes, or until the sauce becomes thick and is the consistency of tomato ketchup.
4) Place aubergine slices in a deep baking tray in a single layer. Generously brush the top of each slice with the tomato sauce. Mix together cumin, black salt, mango powder and chilli flakes, and sprinkle on top of the aubergine slices. Seal the tray tight with aluminum foil. Bake in a preheated oven for 20 minutes at 140C.
5) Serve with a dollop of thickened yogurt sauce and a sprinkle of the remaining chopped coriander on each slice.
