Boil the banana along with skin, not more than 3 whistle pressure cooker, peel off the scrap and let it be cool, then sliced it carefully as shown in picture.

Take besan and add turmeric powder, chilli powder and salt, mix it well dry. Now coat the pieces of banana in dry besan and fry it.

Now add the grated ginger and garlic in the kadhai and put the chopped onion just after putting the ginger and garlic. Let the onion be golden then add turmeric, chilli and coriander powder. Salt to taste and also add tomato puree. Saute it till the masalas be cooked well.

When masala is cooked then add more water in it bcoz banana will absorb the extra water, so to keep thick gravy add extra water. Now put the fried banana into the gravy and put off the gas flame. Don't boil after putting banana. Garnish with coriander leaves.
