The soul of the countryside in the fish sauce jar
Without a huge media or promotion noise, fish sauce - a rustic fish sauce associated with the lives of farmers in the Northern Delta is still quietly preserved and passed down through many generations in Hai Duong villages.
From being only available on family meals, fish sauce today is gradually becoming a branded specialty, gradually conquering the market.
Shark is a common live cowards in lowland rice fields. The fish chosen for fish sauce must often be large, firm and healthy - because the more fish is spawned, the higher the protein is, the sweeter the meat and the more fish sauce is produced.
After catching them, the fish will be soaked in clean water for a few hours to gradually weaken and release all the dirt, while helping to remove the characteristic mud smell of animals living in the fields.

Ms. Nguyen Thi Hoa - a resident of An Thanh commune (Tu Ky district) has been involved in the fishing profession for more than 20 years. She said: "The fish often live near the edge of the fields and live in clean environments, with chemicals, the fish will leave. To catch fish, you have to go early in the morning, at that time the fish and cows leave the cave a lot. Although it is hard, I feel proud that I am contributing to keeping a rural profession.
The finished fish sauce has a light brown color, thick consistency, and a very characteristic strong aroma. Those who are not used to it are hesitant, but after eating it, they will remember it forever. Just a few drops of fish sauce mixed with lemon, garlic, and chili is enough to bring rice, making the boiled vegetables and green rice suddenly become unforgettable. For many Hai Duong people living far from home, the flavor of fish sauce is the scent of memories, the "spiritual specialty" of the Northern countryside.

We have to pay more attention from cleaning, bottling to labeling. City customers are very interested in traditional products, as long as they are clean and of clear origin".

Making fish sauce is not difficult, but to preserve the traditional flavor, the maker must be meticulous, patient and understand the natural fermentation principles.
