Make the Sprouts Batter: Drain the soaked and sprouted green moong completely. Transfer to a blender jar along with ginger, fresh coriander, sooji, Greek yogurt, salt, and a small splash of water. Blend into a smooth, thick batter.
Prepare the Steamer: Heat water in your idli steamer over medium-high heat. Lightly grease the idli mold plates with oil or ghee.
Activate & Pour: Sprinkle 1/2 tsp Eno fruit salt over the batter and gently mix in one direction until frothy. Immediately scoop the batter into the greased idli molds.
Steam the Idlis: Place the idli stand into the steamer, cover tightly, and steam on medium-high heat for 12-15 minutes until a toothpick inserted comes out clean.
Prepare the Chutney: Sauté urad dal, chana dal, garlic, onion, and tomatoes in a pan until soft. Blend with red chili powder, tamarind, salt, and water into a smooth dip.
Serve: Gently scoop out the idlis with a wet spoon and serve hot with tomato-dal chutney and a drizzle of ghee!
