உருட்டு உளுந்து (Uruttu Ulundhu) refers to whole black gram or whole urad dal in Tamil. Unlike split urad dal, this variety retains its black outer skin, giving it a richer, earthier flavor and texture. Whole urad dal is often used in traditional South Indian dishes like idli, dosa, and ulundhu sadam. It is a great source of protein, fiber, and essential minerals, making it a healthy choice. Its creamy texture when cooked makes it ideal for curries and stews, while its robust flavor pairs well with spices.
