Soft, savoury fermented rice and lentil cakes studded with fresh coconut, herbs, and crisp lentils, infused with a fragrant spiced oil. They make a pillowy, gently spiced snack or light meal.
Soak 360 g rice and 200 g urad dal in separate bowls of water for 6 hours.
Drain the soaked rice and blend with 375 ml of water until it forms a slightly coarse batter, then transfer to a large mixing bowl.
Drain the urad dal and blend with 250 ml of water until completely smooth. Stir the dal batter into the rice batter, season with salt to taste, and set aside to ferment for 10 hours until aerated and thick yet pourable, adding a splash of water if required.
About 1 hour before cooking, soak 50.4 g chana dal in water. Drain thoroughly, then fold the soaked chana dal, 128 g fresh coconut, 12 g ginger, 24 g green chilli, and 3 g coriander leaf into the fermented batter.
Heat 9 g vegetable oil in a small frying pan over medium heat. Add the tempering spices and 1 g curry leaf, frying for about 1 minute until the mustard seeds crackle, then stir the hot tempering directly into the batter.
Grease idli moulds (or small heatproof ramekins) with vegetable oil. Spoon roughly 4 tablespoons of batter into each cavity.
Steam in a steamer or an unweighted pressure cooker for 15 to 20 minutes, until a skewer inserted in the centre emerges clean. Let the idlis rest for 1 to 2 minutes before unmoulding.
Use 50% to 60% of the weight, soaked in equal parts warm water for 15 minutes before grinding. Works well for chutneys, though texture is slightly finer and sweeter.
Use 1.2 times the weight in curries. Adds creamy richness and authentic flavour, but makes gravies smoother and eliminates the grated, chewy mouthfeel.
Use the same weight. The seeds are smaller and hotter; fry in hot oil until they pop, about 20–30 seconds, and reduce the heat if they darken too fast. The dish will be a little sharper.
Use 70% of the weight of whole seed, added with the other ground spices rather than fried whole. You lose the popping texture and the heat comes through more evenly.
