What is the crucial purpose of soaking Urad Dal thoroughly and then discarding the soaking water?

Answer

To leach out gas-producing compounds

Proper preparation of Urad Dal mandates a long soaking period, typically overnight or for 6 to 8 hours, followed by completely draining and discarding the water used for soaking. This step is vital because the soaking process facilitates the leaching of water-soluble compounds, particularly the gas-causing agents like oligosaccharides, into the water. Removing this water significantly mitigates the risk of digestive distress, making the subsequent cooking and consumption much easier on the stomach.
