I tried it and found it different:
1 Kg mutton
Fennel green - one big piece of abou 200 grams - finely chopped
Green coriander - one bunch - finely chopped
Green chillies - 12 finely chopped
Garlic whole
Black illachi - 4
6 cup water
Boil all this stuff for 2 hours. Then take it out the meat and blend rest of the stuff and squeeze the garlic.
Fry 4 onions in oil and the separate it from oil and add some garam masala (whole - with bay leaves) and meat and fry it for few minutes and then add pre-soaked rice (4 cups) and then add back the yakhnai (6 cups) and cook and when almost done simmer for10 mins and if you like add kewra and zarda colour.
