Orid Dal (Black Urad Dal) plays a key role in giving Idli its soft, fluffy and spongy texture . The quality of the dal directly affects how well the batter absorbs water, grinds, ferments and traps air. 1. Better water absorption Good-quality Orid Dal absorbs water evenly during soaking. Proper hydration helps the dal grind into a smooth, aerated batter. 2. Better grinding and batter texture Fresh, good-quality Orid Dal can produce a smooth and fluffy batter . If the dal is old, excessively dry or damaged, it may not grind as effectively, resulting in heavier batter. 3. Stronger fermentation Orid Dal supports fermentation by providing nutrients and creating a batter structure that can retain the gases produced during fermentation. Good-quality dal generally helps produce a well-fermented batter. 4. Better air retention One of the most important properties of Orid Dal is its ability to help the batter trap and retain tiny air bubbles . These bubbles expand during steaming,...
