kings of the
Indianised kingdoms might have invented the steamed idli there, and brought the recipe back to India during 800–1200 CE.
Achaya mentioned an Indonesian dish called "kedli", which according to him, was like an idli.
However, Janaki Lenin was unable to find any recipe for an Indonesian dish by this name. According to food historian
Colleen Taylor Sen the fermentation process of idli batter is a natural process that was discovered independently in India, since nearly all cultures use fermentation in some form.
The
Gujarati work ''Varṇaka Samuccaya'' (1520 CE) mentions idli as ''idari'', and also mentions its local adaptation, ''idada'' (a non-fermented version of
dhokla).
The earliest extant
Tamil work to mention idli (as ''itali'') is ''Maccapuranam'', dated to the 17th century.

'') are soaked separately for at least four hours to six hours or overnight. Optionally spices such as fenugreek seeds can be added at the time of soaking for additional flavour. Once done soaking, the lentils are ground to a fine paste and the rice is separately coarsely ground, then they are combined. Next, the mixture is left to ferment overnight during which its volume will more than double. After fermentation, some of the batter may be kept as a starter culture for the next batch. The finished idli batter is put into greased moulds of an idli tray or "tree" for steaming. The perforated molds allow the idlis to be cooked evenly. The tree holds the trays above the level of boiling water in a pot, and the pot is covered until the idlis are done (about 10–25 minutes, depending on size). A more traditional method is to use leaves instead of moulds.

Serving
Since plain idlis are mild in taste, a condiment is considered essential. Idlis are often served with
chutneys (coconut-based),
sambar and
Medu vada. However, this varies greatly by region and personal taste, it is also often served with kaara chutney (onion-based) or
spicy fish curries. The dry spice mixture
podi is convenient while travelling.
Variations
There are several regional variations of idlis made in South India and Sri Lanka. With the emigration of south Indians and Sri Lankans throughout the region and world, many variations on idli have been created in addition to the almost countless local variations. Hard-to-get ingredients and differing cooking customs have required changes in both ingredients and methods.
Parboiled rice can reduce the soaking time considerably. Store-bought ground rice or cream of rice may also be used. Similarly,

may be used for preparing
rava idli (wheat idli).
Dahi (yogurt) may be added to provide the sour flavour for unfermented batters. Pre-packaged mixes allow for almost instant idlis.
In addition to or instead of fenugreek, other spices may be used such as mustard seeds, chili peppers, cumin, coriander, ginger, etc. Sugar may be added to make them sweet instead of savoury. Idli may also be stuffed with a filling of potato, beans, carrot and masala. Leftover idlis can be cut-up or crushed and
sautéed for a dish called idli
upma. A microwave or an automatic electric steamer that is non-stick is considered to be a convenient alternative to conventional stovetop steamers. Batter preparation using a manual rocking rock grinder can be replaced by electric grinders or blenders. Many restaurants have also come up with fusion recipes of idlis such as idly manchurian, idly fry, chilly idly, stuffed idly, to name a few.

Batter fermentation
Fermentation of idli batter results in both leavening caused by the generation of carbon dioxide as well as an increase in acidity. This fermentation is performed by lactic acid bacteria, especially the heterofermentative strain ''
Leuconostoc mesenteroides'' and the homofermentative strain ''
Enterococcus faecalis'' (formerly classified as ''Streptococcus faecalis''). Heterofermentative lactic acid bacteria such as ''L. mesenteroides'' generate both lactic acid as well as carbon dioxide whereas homofermentative lactic acid bacteria only generate lactic acid.
Both ''L. mesenteroides'' and ''E. faecalis'' are predominantly delivered to the batter by the black gram. Both strains start multiplying while the grains are soaking and continue to do so after grinding.
''L. mesenteroides'' tolerates high concentrations of salt unlike most other bacteria. Hence the salt in the batter and the ongoing generation of lactic acid both suppress the growth of other undesirable micro-organisms.
Idli Day
March 30 is celebrated as World Idli Day. It was first celebrated in 2015 at Chennai.
