In a pan, take the minced mutton and add salt, turmeric powder chilli powder to it, cover the pot and let it simmer. There is no need to add water as the keema leaves water that's required for the meat to get cooked.
Check if the mutton is cooked and the water is absorbed. Meanwhile, pour a little oil into a pan and fry with fennel, chopped onion.
Once the onion becomes soft, add the cooked mutton keema and then the mashed boiled potatoes.
Check the salt needed for this mixture and pat it into a cutlet shape.
Beat the egg in a bowl and mix it with Salt and Pepper. Dip the patties in egg and shallow fry in oil.
Flip and cook each side to make it to a super yummy mutton cutlet.
