Prepare Gatta Curry mixture by adding flour, ginger, cumin seeds and baking soda in a mixing bowl stirring well to combine.
Add red chilli powder and water. Mix to a thick consistency.
Add fresh mint leaves and mix well to combine.
Coat each frozen K&N's Seekh Kabab with this mixture and set aside.
Boil water in a sauce pan, and add coated Seekh Kababs.
Cook 10 to 15 minutes and set aside, retaining the Gatta Curry coating that will separate from Seekh Kababs. Drain the water.
In a separate pan, combine yoghurt, onion, turmeric powder, coriander powder, cumin seeds, red chilli powder and salt.
Cook for 5-6 minutes while stirring.
Pour in Gatta Curry mixture and cook 4-5 minutes more to combine flavours, stirring continuously.
Add Seekh Kababs, cooking oil, whole red chilli and cook on low heat until gravy thickens.
Add garam masala and serve with chapati.
