2. The traditional making process of Phu Quoc fish sauce
The traditional making process of phú quốc fish sauce is a time-honoured method that relies on natural fermentation to create a distinctive and rich flavour. Here’s an overview of the steps involved:
Selection of Ingredients: Although fish sauce can be made from many kinds of fish and sea creatures, the most common one is anchovies. The process begins with the selection of high-quality anchovies, which are abundant in the waters around Phu Quoc. These small fish are preferred for their high protein content and optimal oil ratio, which contribute to the sauce's robust flavour.
Salting: After carefully selecting the fish and salt, the fish will be mixed with salt in the "perfect" ratio of 3:1. That means for every 3 tons of anchovies, mix with 1 ton of salt. In Phu Quoc, the widely accepted fish-to-salt mixing ratio is considered optimal for producing the finest fish sauce. This mixture is crucial for initiating the fermentation process.
Fermentation: The salted anchovies are transferred to large wooden barrels called "thùng gỗ" in vietnamese. The barrels are made from tropical wood, which contributes to the unique taste of the sauce. The fish and salt mixture is left to ferment under natural conditions for at least 12 months, and often up to 18 months. During this time, the fish slowly breaks down in the presence of salt, releasing its flavours into the liquid.
Extraction: After the fermentation period, the fish sauce (nước mắm) is extracted. The liquid is naturally pressed out from the decomposition of the fish under its own weight. This first extraction, known as "nước mắm nhĩ," is considered the highest quality fish sauce and is highly prized for its rich flavour and clear, amber colour.
Refinement: The extracted fish sauce may undergo further refinement to remove impurities and enhance clarity. It can also be aged further to develop more complex flavours.
Bottling: Once sauce nuoc mam phu quoc reaches the desired taste and quality, it is bottled and prepared for distribution. The bottling process is done carefully to preserve the sauce's flavour and extend its shelflife.
The traditional method of making Phu Quoc fish sauce is labour-intensive and requires a deep understanding of the fermentation process. This meticulous approach ensures that the final product enhances any dish it accompanies with its potent and unique flavour, embodying the essence of Vietnamese cuisine.
