The fenugreek seeds soaked with the urad dal are not for flavor, they are the fermentation engine. They feed the wild yeast that makes the batter rise overnight, which is the whole difference between airy idli and dense pucks.

The Method
SoakSoak rice separately, and urad dal with fenugreek, for at least four hours.
GrindGrind dal to a light fluffy paste, then rice to a slight grit; combine with salt.
FermentCover and leave in a warm spot 8 to 12 hours until doubled and bubbly.
SteamLadle into greased idli molds and steam 10 to 12 minutes until a tester comes clean.
UnmoldRest two minutes, then spoon out and serve hot with chutney and sambar.
Can you make Idli in an air fryer? — Yes, with an insert
Not on its own — an air fryer can’t hold a pool of liquid. You can simmer it in an oven-safe dish or a silicone insert made to fit the basket, but the broth won’t reduce or brown the way it does on the stove, and that insert comes out scorching, so use oven mitts. For real depth, a pot on the stove wins.
Can you freeze Idli? — Yes
Yes — it freezes well. Cool it fully, portion into airtight containers, and it keeps a few months; thaw in the fridge and reheat gently.
Can you make Idli ahead of time? — Yes
Yes — it holds well and often tastes better the next day. Make it ahead and reheat gently before serving.
Is Idli gluten-free? — Yes
Yes — nothing in this recipe as written contains gluten. As always, glance at the labels on any packaged items (broth, sauces, chocolate), since brands vary.
Is Idli vegan? — Yes
Yes — no meat, seafood, dairy, egg, or honey in it as written.
