In developing the recent post "Chennai, formerly Madras, India" (here), I came upon the above video. I did not know what an "idli" was. I looked them up and went in seach of a restaurant serving them in SE Portland. I found them at the Dwaraka Indian Cuisine restaruant on SE Hawthorne, only they served them for dinner not for breakfast and not for lunch.
From Wikipedia (here):
Idli , also romanized idly or iddly, plural idlis, is a savory cake of south Indian origin popular throughout India. The cakes are usually two to three inches in diameter and are made by steaming a batter consisting of fermented black lentils(de-husked) and rice. The fermentation process breaks down the starches so that they are more readily metabolized by the body.
Most often eaten at breakfast or as a snack, idlis are usually served in pairs with chutney, sambar, or other accompaniments. Mixtures of crushed dry spices such as milagia podi are the preferred condiments for idlis eaten on the go. A variant of Idli known as sanna is very popular amongst the Goans and other Konkani people.
