Resting biryani for 15-20 minutes after cooking allows the steam to redistribute, ensuring the rice grains separate and the flavors meld together for a more cohesive and flavorful dish.
When biryani is cooked, a significant amount of steam is trapped within the pot. This steam can make the rice grains sticky and mushy if the biryani is served immediately. Resting allows the steam to gently dissipate, preventing the rice from becoming overcooked and clumping together. During this resting period, the residual heat continues to cook the biryani very gently, allowing the flavors of the rice, meat, and spices to further integrate and deepen. This results in a more balanced and harmonious taste profile. The resting time also helps the rice grains to firm up slightly, improving the overall texture of the biryani.
Resist the urge to stir the biryani immediately after turning off the heat. Stirring while the biryani is still very hot and steamy can break the rice grains and make the dish mushy. Let it rest undisturbed for the recommended time before gently fluffing with a fork.
