Re: Biryani disasters
For biryani, take same amount of rice as chicken so if chicken is 1 kg then rice should be 1 kg as well. One kg rice should be around 4 cups(get the proper measuring cup if you don't have it already!).
For dam, if you're burning your rice then heat is probably too high, use low setting and also put the first layer of salan instead of rice. Keep lid closed, DO NOT take it off and on during the dam(30-45 mins is good).
