Crisp, fermented rice-and-lentil crepes folded around a gently spiced, savoury potato filling. They offer a balance of tang from fermentation and warmth from fried spices.
Place 600 g basmati rice and 200 g urad dal into separate bowls, cover generously with water, and leave to soak overnight.
Drain the rice and dal. Blend the rice in a food processor until smooth, then transfer to a large mixing bowl. Blend the dal until smooth, add it to the rice, mix thoroughly with salt to taste, cover with a damp cloth, and leave to ferment overnight in a warm spot.
Boil 250 g potato in water for about 15 minutes until tender. Drain, let cool, peel off the skins, and mash smooth.
Warm 27 g vegetable oil in a frying pan over medium heat. Add 1 tsp mustard seeds, 4.2 g chana dal, and 2.5–3 g curry leaf, cooking for 3 minutes. Add 150 g onion and sauté for 2 minutes. Stir in the ground spices for the filling and cook for 2 to 3 minutes, then mix in the mashed potato and 15.3 g lemon juice until uniform.
Stir enough water into the fermented rice and lentil batter to achieve a thick, pourable consistency.
Heat a cast-iron griddle or flat tawa over medium heat and grease lightly with 250 g ghee or vegetable oil. Ladle two tablespoons of batter onto the middle, rapidly spreading it outward in a circular motion to create a 15 cm disc.
Trickle a little ghee or oil around the perimeter. Cover with a lid and cook for 1 minute until the base turns golden and crisp, then flip and cook the other side briefly.
Spoon some potato filling across the middle, fold the crepe over, and serve hot with coconut-tomato chutney and sambhar. Repeat with the remaining batter and filling.
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.
Chana dal
Yellow split peas
Use 100% of the weight. Soak for at least 1 hour; takes about 10 minutes longer to cook through and has a marginally earthier flavour.
Use 80% of the weight, finely shredded and browned slowly with a pinch of asafoetida. Replicates the bulk and natural sweetness in gravies without allium.
Steep a tiny pinch (0.1 g per 2 g turmeric) in 2 tbsp warm water; use to match the rich golden hue. Contributes an aristocratic, honeyed floral flavour rather than earthy bitterness.
