• Cut the baby brinjals lengthwise in the shape of wedges. Keep these pieces immersed in water so that they don't blacken.

• Once they stop spluttering add the ginger and garlic paste and saute for a minute on low flame.
• Add the coriander powder, turmeric powder and chilli powder and fry for 2-3 seconds.
• Add the vinegar, tomatoes and tomato ketchup and mix well. Saute until the tomatoes are mashed well and the oil layer shows up.
• Drain the brinjal pieces from water and add it to the masala. Add salt, mix well and cook until the brinjals are soft and cooked well.
• Remove from fire and transfer onto a serving dish.
• Garnish with chopped coriander leaves.
