Soft, spongy idlis with no overnight fermentation. Ground oats, rava and curd, a quick tadka and a spoon of fruit salt, steamed in 12 minutes flat.

Soft oats idlis flecked with carrot and coriander on a steel plate with coconut chutney and a bowl of sambar

Ingredients

  • 1 cup (90 g) quick oats
  • ½ cup (85 g) fine semolina (rava)
  • ½ cup (120 g) thick curd, lightly sour is best
  • ¾ to 1 cup (180–240 ml) water
  • 1 tbsp (15 ml) oil, plus a little for greasing
  • ½ tsp mustard seeds
  • 1 tsp (5 g) chana dal
  • 1 tsp (5 g) urad dal
  • 8 curry leaves, chopped
  • 1 green chilli (4 g), finely chopped
  • 1 tsp (5 g) ginger, grated
  • 1 small carrot (60 g), finely grated
  • 2 tbsp coriander leaves, chopped
  • 8 cashew halves (10 g), optional
  • Salt, to taste (about ¾ tsp)
  • 1 tsp (5 g) fruit salt (Eno), or ½ tsp baking soda

Method

  1. 1Dry-toast the oats in a pan on medium-low heat for 3 minutes until fragrant. Cool for a few minutes, then grind to a slightly coarse powder. Toast the rava in the same pan for 2–3 minutes, stirring, until it smells nutty but stays pale.
  2. 2Heat the oil in a small pan. Pop the mustard seeds, then add chana dal and urad dal and fry until golden. Add the curry leaves, green chilli and ginger, give it 20 seconds, and switch off.
  3. 3In a large bowl combine the oat powder, rava, curd, carrot, coriander and salt. Pour the tadka over, then add ¾ cup water and whisk into a thick batter that drops slowly from a spoon.
  4. 4Cover and rest the batter for 15 minutes. Meanwhile, grease the idli moulds and bring 2 inches of water to a boil in the steamer or pressure cooker (whistle removed).
  5. 5After resting the batter will have thickened. Loosen it with a few spoons of water until it is like thick idli batter again.
  6. 6Sprinkle in the fruit salt with 1 tsp water, stir gently in one direction for a few seconds until the batter turns frothy, and fill the moulds right away, about three-quarters full. Press a cashew half onto each if using.
  7. 7Steam on medium-high for 11–12 minutes. A toothpick pushed into the centre should come out clean.
  8. 8Switch off and let the moulds sit for 5 minutes before running a wet spoon around each idli to release it.

Notes from the Department

  • Grind the oats coarse, not to a flour. Too fine and the idlis turn dense and pasty.
  • Add the fruit salt only when the steamer is boiling. The bubbles start fading the moment it hits the batter.
  • Sour curd gives the slight tang fermented idlis have. Leave fresh curd on the counter for a few hours if that is all you have.
  • Leftover idlis make excellent podi idli: cut into quarters and toss in a hot pan with ghee and idli podi.

Why this works

Traditional idli batter takes a day: soak, grind, ferment. This version gets its lift from fruit salt instead, which releases carbon dioxide as soon as it meets moisture. Curd brings the gentle sourness that fermentation would have produced, and a short rest lets the oats and rava absorb liquid so the idlis set properly instead of crumbling. The result is lighter than rava idli and softer than you would expect from oats.

Toasting matters twice here. Toasted oats lose their raw, cereal taste, and toasted rava stops the batter from turning gummy. The tadka goes in for flavour and texture; crunchy bits of chana dal in a soft idli are the point. It is honestly a different food from a fermented idli, and the Department of Steaming does not pretend otherwise. It is just very good on a weekday.

Swaps

Rolled oats work if you grind them the same way. Swap carrot for finely chopped beans, peas or grated beetroot, which turns the idlis a cheerful pink. Baking soda can stand in for fruit salt; use half the quantity and add a squeeze of lemon. To make them vegan, replace curd with ½ cup thick coconut milk plus 1 tbsp lemon juice, though the texture is slightly more delicate.

Serving and storage

Serve hot with coconut chutney, tomato chutney or a bowl of sambar. These idlis also pack well in a lunch box with a small jar of podi.

They keep in the fridge in a closed box for up to two days. Re-steam for 3–4 minutes, or microwave covered with a damp cloth for 30–40 seconds, to bring back the softness. The batter itself does not keep once the fruit salt is in, so mix only what you will steam.

Questions people ask

Can I make oats idli without Eno?
Yes. Use ½ tsp baking soda plus 1 tsp lemon juice stirred in just before steaming. The idlis rise a little less but stay soft.
Why are my oats idlis hard or dense?
The usual causes are oats ground too fine, batter that is too thick after resting, or fruit salt added too early. Loosen the batter after the rest and steam immediately after adding the fruit salt.
Do I need to ferment oats idli batter?
No. This is an instant batter. The 15-minute rest is only to hydrate the oats and rava, and the fruit salt provides the rise.
Can I steam oats idli in a pressure cooker?
Yes. Remove the whistle, bring the water to a boil, put in the idli stand and steam for 11–12 minutes on medium-high heat.
