Thicker batter, and do not knock it back

Idli batter is ground thicker than dosa batter and is not thinned before steaming — the carbon dioxide trapped during fermentation is what makes the cakes light. Stirring vigorously after fermentation knocks that gas out and gives you dense pucks. Fold gently, and only if you must.

Notes

  • Grind the urad dal cold, with ice water if your blender runs hot. Heat kills the aeration.
  • Fill moulds three-quarters full; they rise considerably.
  • Leftover idli, torn and fried with mustard seeds and curry leaves, is arguably better than the original.

Try butter, 30 minutes, braise, or an ingredient you need to use up.
