Biryani is a rice dish that is typically cooked in a clay pot. However, you can also cook biryani in a steel cooker. The key to cooking biryani in a steel cooker is to first brown the meat and spices in the bottom of the pot. This will give the biryani flavor and prevent the rice from sticking to the bottom of the pot. Once the meat and spices are browned, add the rice and stock to the pot and stir well. Place a lid on the pot and bring it to a boil over high heat. Once boiling, reduce the heat to low and simmer for 30 minutes. After 30 minutes, turn off the heat and let the biryani sit for 5 minutes before serving.
