To assemble the Biryani, heat oil in a large heavy-bottomed pot.
Spread about half the paneer mix at the bottom of the pot. Then layer over with half of the pre-cooked rice, and top that with half the amounts of the cilantro, mint and fried onions.
Repeat the layering with the remaining half of the ingredients.
Sprinkle the rose water on top, and cook covered on low heat for 10-15 minutes till the rice is completely cooked through. Serve warm with a side of Raita.
