The Art of Khmer Fermented Fish: A Day in Kampot's Prahok Yards

A Sticky, Salty Morning in Kampot

We left Siem Reap before dawn, trading the temple crowds for a five-hour drive south to Kampot province. The air changed as we approached the coast—thicker, saltier, carrying the smell of mud and fish. Our destination was not the famous pepper farms or the riverside bars, but a cluster of stilted wooden houses along the Teuk Chhou River, in the commune of Chum Kiri. Here, in the dry season, the riverbanks turn into open-air factories for one of Cambodia’s most essential foods: prahok, the fermented fish paste that anchors nearly every Khmer meal.

The yards are easy to spot. Long tables shaded by thatch roofs, lined with shallow wooden troughs filled with silvery fish. The smell hits you first—sharp, briny, a little sweet, like the sea left out in the sun. It is not unpleasant, but it demands attention. We were greeted by Mrs. Nary, a grandmother who has been making prahok for over forty years. She laughed at our wrinkled noses and handed us each a small bowl of the greyish paste to taste. It was intense, funky, and strangely moreish, especially when she added a squeeze of lime and a sliver of raw garlic.

The Craft of Fermentation

Prahok begins with the small, bony fish called trey riel (circulating silver fish), caught in the Tonle Sap and Mekong rivers during the rainy season. In Kampot, the fish are smaller and saltier, because the water here is brackish, mixing with the sea. The process is simple but unforgiving. The fish are washed, drained, and mixed with salt—roughly one part salt to three parts fish—then left to ferment in large clay jars for at least a month. After that, the mixture is pounded with a wooden pestle until it becomes a smooth paste, then packed into smaller jars for aging.

Mrs. Nary showed us her jars, lined up under the house like soldiers. Some had been fermenting for six months, others for two years. The older the paste, the deeper the flavor, she explained. She lifted the lid of a two-year-old jar and the smell was almost floral, with a nutty undertone. We watched as her daughter-in-law Srey Leak sorted the day’s catch, tossing aside any fish with dull eyes. Only the freshest fish make good prahok, she said, because the fermentation magnifies every flaw.

A Taste of the River

By late morning, the heat was pressing down, and the women moved their work into the shade. We joined them for a simple lunch of prahok ktis—a rich dip of prahok, pork, coconut milk, and kaffir lime leaves—served with fresh cucumbers, green mango, and sticky rice. The dip was creamy and salty, with a gentle funk that paired beautifully with the sharpness of the mango. We ate with our hands, scooping the paste onto rice, watching the riverboats drift by.

After lunch, we walked through the village of Prek Tnaot, just a few kilometers upstream. Here, the yards are smaller, family-run, and the prahok is often sold directly to neighbors and local markets. We stopped at a small shack where a man was frying fresh fish cakes—prahok mixed with minced pork and herbs, then deep-fried until golden. He sold them for a few hundred riel each, and we ate them hot, the crispy exterior giving way to a soft, savory center. It was the best thing we tasted all day.

Getting there

From Kampot town, head east along the river road toward Chum Kiri commune. The drive takes about 30 minutes by motorbike or tuk-tuk. You will see the prahok yards on the river side, especially in the dry season (November to May), when the water level drops and the fish are abundant. Ask your guesthouse in Kampot to arrange a driver, or hire a motorbike if you are comfortable on two wheels. The roads are paved but narrow, and you will share them with cattle, bicycles, and the occasional truck.

Good to know

The best time to visit is early morning, between 7 and 10 am, when the women are sorting and salting the fish. By noon, most families have moved to other chores.
Prahok is an acquired taste, but do try it at least once—either in a dip, a stir-fry, or a soup. It is the backbone of Khmer cuisine, and every family has their own recipe.
Bring a small container if you want to buy prahok to take home. Prices vary, but a small jar (about 500 grams) is affordable; ask your host to help you negotiate.
Wear old clothes and closed-toe shoes. The fish scales and salt water will stick to everything, and the ground can be slippery.
