I learnt this from a friend. I tried it for the first time at home and everyone liked it and this was so easy. You don't have to cut it thin or you can even use the frozen cut okra. That saves a lot of time and this doesn't reduce much in quantity either, when it is cooked.
Okra - 500gms (cut into 1 inch pieces)
Onion - 1 medium
Kokum - 4 pieces (cut into smaller pieces)
Redchilli powder - 1 tsp (adjust as per your taste)
Salt - to taste
Mustard seeds, curry leaves and hing for seasoning
Soak the kokum in couple of spoons of warm water for few minutes. In a pan, heat a spoon of oil and when it is hot, add mustard seeds and let it splutter. Add curry leaves and hing and saute for few seconds. Add cut onions and kokum and saute till the onions are translucent. Add the okra, red chillipoweder, salt and cover and cook for few minutes, until the okra is well cooked. Remove the lid and cook for some more time till you get a dry curry.
Goes well with both Rice and Roti.
Kokum has sour taste like tamarind and is considered to be better than tamarind as it has some medicinal properties and is used in maharashtrian and konkani cuisine.
