Pull the stigma (the small stem like part inside) out of the flowers. Wash them well under running water to remove dirt/worms. Pat them dry and keep aside. In a mixing bowl, mix together the gram flour, nigella seeds, turmeric powder, chilli powder and salt
Add water gradually to form a batter of dropping consistency, simultaneously keep a cooking pot with the oil to heat. Add a tablespoon of the hot oil to the batter, mix well, dip each flower in it, let any excess batter drop and then drop them in the oil
Deep fry each of them, in batches, until golden brown and remove on an absorbent kitchen towel. Serve these lip smacking kumro phuler bora (pumpkin blossom fritters) as a snack or a side dish with rice and dal. Enjoy!
