River fish cured with salt, rice and garlic until sour, then grilled or fried. It is a Lao household preserve made when the Mekong catch is heavy, packed in jars for the dry months.
It is an ambient ferment of raw freshwater fish in a sealed jar, safe only if the acidity arrives fast enough — and Mekong fish carry liver fluke that souring does not reliably kill.
What goes into it
- freshwater fish
- salt
- cooked rice or roasted rice powder
- garlic
How it is made
The fish is cleaned, salted for a day, then packed into a jar in layers with cooked rice and garlic, weighted and sealed. Lactic bacteria feed on the rice starch and acidify the jar over days to weeks, souring and preserving the fish. It is always cooked before eating.
How long it takes: several days to several weeks in the jar
How it is eaten
Grilled in banana leaf or fried, with sticky rice and fresh herbs.
