It contains high levels of dietary fiber to support smooth digestion and healthy weight management. This heritage rice is also packed with minerals such as iron, magnesium, and zinc, which boost immunity, regulate metabolism, and support heart health. Its unpolished nature helps retain nutrients that promote detoxification and stable blood sugar levels.
To make soft idlis and crisp dosas, soak Karunkuruvai rice for 6–8 hours and urad dal with fenugreek seeds for 3–4 hours. Grind the urad dal until fluffy and grind the rice to a slightly coarse texture. Mix both with salt and let the batter ferment overnight for 8–12 hours. Steam the batter for idlis or dilute it slightly to prepare thin, crispy dosas. This traditional method enhances flavor, texture, and nutrition.
