Pulao made with plain water has a milder flavor and a drier, more separate texture, while pulao made with stock (yakhni) is richer in flavor, more moist, and has a slightly stickier texture due to the infused fats and proteins.
The liquid used to cook pulao significantly impacts its final flavor and texture. When plain water is used, the rice primarily absorbs water, resulting in a cleaner, less complex flavor profile. The grains tend to remain more separate, creating a drier texture. This is because there are no additional fats or proteins to coat the rice grains and contribute to a creamier consistency.
In contrast, using a rich vegetable or meat stock (yakhni) infuses the rice with a depth of flavor derived from the vegetables, herbs, spices, and/or meat used to prepare the stock. The fats and proteins present in the stock are absorbed by the rice, leading to a more moist and slightly stickier texture. The stock also contributes umami and savory notes, making the pulao significantly more flavorful and aromatic. The rice grains are coated with the stock's components, resulting in a richer mouthfeel.
Always use homemade or high-quality store-bought stock for the best flavor. Avoid overly salty or artificially flavored stocks, as they can negatively impact the final taste of your pulao.
