Take a pan and put 5 tbsps of vegetable oil (absolutely no olive oil)
Once oil is hot put half teaspoon of shahi jeera
Add cinnamon half inch and cloves
Add chopped onions immediately (to avoid burning of the spices)
Add turmeric and saute onions until transparent
Add 1 tablespoon of ginger garlic paste and keep sautéing the onions until brown
Add chicken to the fried onion and mix thoroughly
Then Grind cashews very fine and add the cashew powder to the mixture
Add salt to taste, red chilli powder (1tsp) based on taste and garam masala
Add half cup yogurt to the marinade and mix thoroughly
Add lime or lemon juice
Keep mixing thoroughly so all spices and chicken are marinated
Keep the marinade aside for one hour at least. The marinade should look something like this. The difficult part of the biryani is over.
