Make a paste of the turmeric powder with very little water. Keep aside.
Heat the remaining mustard oil in a pan. Throw in the dry red chillies, bay leaves , crushed cardamom, cloves and cinnamon, allow the spices to splutter and release their aroma.
Add the onions, fry over medium heat for 10-15 minutes until the onions turn a light translucent brown.
Now add the red chilli paste, turmeric paste, remaining ginger garlic paste, continue to cook over medium heat for 8-10 minutes until the masala starts to release oil.
Add the marinated duck and fried onions, give it all a hearty stir.
Cover and cook over medium flame, stirring occasionally. The meat shall release water as it cooks, so no need to add any water at this stage.
Once the water released by the meat has almost dried, pour in 1.5 cups of warm water. Throw in the slit green chillies. Continue to cook over medium untill the duck meat is tender . If it’s getting too dry, you can add a splash of warm water in between.
Finish with a generous sprinkle of garam masala, serve with Chita ruti
