Fermented milk from Chilika lake, Odisha, India
Chilika curd is a thick, sour buffalo-milk curd from the shores of Chilika lake in Odisha. Milk of the Chilika buffalo is boiled down for a long time and poured into a woven bamboo bowl sealed with dried layers of old curd, then covered with leaves to set. It keeps well at room temperature for about a week.
| Chilika buffalo milk | High in fat (8.6 %), pH 6.59, acidity 0.09 % lactic acid; concentrated by long boiling[nanda2013][mohanty2017] |
| Curd from an earlier batch | Dried in layers onto the bamboo bowl, which then seeds each new batch[nanda2013] |
| Starter | backslop: the bamboo bowl is coated with layers of inoculum curd |
What changes: Layers of curd dried in the sun seal a fresh woven bamboo bowl
The bowl is coated with curd and dried in the sun, again and again, building up several layers. Output: sealed, seeded bamboo bowl.

It keeps well at room temperature for about a week. Lactobacillus and Leuconostoc do most of the fermenting.

Chilika curd is set in a woven bamboo bowl sealed and seeded with dried layers of old curd, from long-boiled, very fat buffalo milk, and it keeps for about a week without chilling.
The milk is boiled for a long time before setting. Antifungal lactobacilli are proposed as one reason the curd keeps about a week at room temperature.
Every number is labelled with how it is known. How this atlas is made
Nanda et al. (2013) tell that about 400 years ago the saint poet Purushottam Das wrote a poem of Krishna dancing with a milkmaid, Maniki, who had come to sell curd on the banks of Chilika. They proposed the curd for Geographical Indication registration.
