Ghee adds richness and aroma, milk helps steam the rice gently and evenly, and kewra water infuses a delicate floral fragrance to the biryani during the 'dum' cooking process.
The 'dum' cooking method, crucial in biryani preparation, involves slow cooking in a sealed container. Adding ghee, milk, or kewra water to the final rice layer before sealing the pot serves specific purposes:
Ghee: Ghee, or clarified butter, is a staple in Indian cuisine. When drizzled over the rice, it melts and permeates through the layers during the 'dum' process. This imparts a rich, nutty flavor and a luxurious texture to the biryani. The fat content also helps prevent the rice from drying out.
Milk: A splash of milk adds moisture and helps to gently steam the rice. The steam created by the milk ensures that the rice cooks evenly and becomes fluffy. It also contributes a subtle sweetness and creamy texture to the overall dish.
Kewra Water: Kewra water, extracted from the pandanus flower, is a fragrant essence. A few drops added to the rice layer infuse the biryani with a delicate floral aroma, enhancing the sensory experience. It's a subtle addition that elevates the dish's complexity.
These additions are not just about flavor; they are integral to the texture and overall quality of the biryani, ensuring a moist, flavorful, and aromatic final product.
Use full-fat milk for the best results, as the fat content contributes to a richer and more flavorful biryani. Skim milk will not provide the same level of moisture and richness.
