Cut off the ends and make a long lengthwise slit on each okra and check if it is good from inside.
Heat cooking oil in a nonstick pan and fry okra for 5 minutes on medium heat till soft but not fully cooked.
Remove from pan and set aside. In the same pan add more oil and add cumin seeds. Once it starts to change color, add chopped onion and saute until light pink.
Then add 2 teaspoon ginger garlic paste, green chili, 1 1/2 teaspoon red chili powder, 1 1/2 teaspoon coriander powder, 1/4 teaspoon turmeric powder, 1 tablespoon kasoori methi and fry for 2 minutes on low flame.
Now add chopped tomato and salt and cook until tomato is wilted and well blended with rest of the masala.
Finally, add fried okra, amchur powder, and chopped coriander leaves. Stir well and cook covered for 10 minutes on low heat or till the vegetable is fully cooked. Taste and adjust the seasoning.
Serve hot with the main course or with roti/chapatti.
