What are some best practices to prepare biryani

Preparing biryani is more of an art. And results continue to improve as you start taking cues from various aspects of the ingredients being used. Most important steps that could lead to quality issues are around managing moisture while protein cooks. Especially when you use chicken. Chicken tends to release a lot of moisture and that can spoil the dish. A recommendation would be to cook all of the chicken 50% through without any seasoning in a separate pot. It'll release significant moisture in this process. Once done, you can then separate out chicken from the stock and use the chicken for Biryani. One of the other gotcha while cooking Biryani is while preparing rice. Rice should never be fully cooked before it's mixed with chicken. Remember that rice and seasoned chicken has to be cooked together for several minutes. To get best results make sure you cook rice in boiling water only 70% through. It should be bit uncooked. Then use that rice to mix with seasoned chicken and continue following the Biryani recipe from that point onwards.
