This traditional condiment brings the deep, salty-sweet complexity that defines authentic Chinese cooking to your kitchen. Over years of testing, I’ve refined a method that captures the essence of fermented fish without the lengthy aging process.
The foundation is high-quality fish combined with salt and water, then fermented for 6 months to develop its signature umami depth. The result is a liquid gold that enhances stir-fries, marinades, and dipping sauces with unmatched richness.
What you’ll create is a versatile seasoning that adds layers of savory flavor to any dish. It’s the secret weapon in many classic Chinese recipes, delivering that restaurant-quality taste you’ve been missing at home.
Use it sparingly—this potent sauce packs a punch of authentic flavor in every drop.
Ingredients for Chinese Fish Sauce
A handful of simple ingredients transform into a complex, umami-rich condiment with authentic depth.
| Ingredient | Amount | Notes |
|---|---|---|
| Fresh Anchovies 🐟 | 1 lb | Whole, ungutted, food-grade |
| Sea Salt 🧂 | ½ lb | Coarse, non-iodized preferred |
| Water 💧 | 2 cups | Filtered or distilled |
| Sugar 🍬 | 2 tbsp | Optional for balanced flavor |
| Rice Wine 🍶 | ¼ cup | Shaoxing wine preferred |
| Garlic Cloves 🧄 | 4 cloves | Smashed, unpeeled |
| Fresh Ginger 🌿 | 2 oz | Sliced, unpeeled |
| Dried Chili Peppers 🌶️ | 2 whole | Optional for heat |
The anchovies are non-negotiable here. Whole, ungutted fish ferment best—look for fresh anchovies at Asian markets or specialty seafood counters. If fresh aren’t available, high-quality frozen work too (thaw completely first). The salt must be non-iodized to avoid bitterness. I always use Diamond Crystal kosher salt for consistency. The water should be filtered to prevent any chlorine interference with fermentation.
No anchovies? Small sardines or mackerel are the closest substitutes, though the flavor profile will differ slightly. Skip the sugar if you prefer a purely savory sauce. Shaoxing wine can be swapped for dry sherry in a pinch. The garlic and ginger add depth but can be omitted if you want a simpler, more traditional version. For heat, Thai bird’s eye chilies pack more punch than standard dried red peppers.
Fermented fish sauce keeps indefinitely at room temperature—6 months minimum for full flavor development. Store in a glass jar away from direct light. A thin layer of oil on top prevents mold. The aroma mellows over time, so don’t be alarmed by the initial pungency. Use within 1 year for peak quality.

Step-by-Step Instructions for Chinese Fish Sauce
This traditional fermentation process transforms simple ingredients into a complex, savory condiment over time.
Step 1: Prepare and Salt the Anchovies
Begin by rinsing the 1 lb Fresh Anchovies under cold water to remove any surface impurities. Pat them dry with paper towels, but don’t remove the heads or guts—they contribute to the depth of flavor during fermentation.
In a large glass jar or food-grade plastic container, create a layer of 0.5 lb Sea Salt on the bottom. Add the anchovies, then cover completely with the remaining salt. This ratio ensures proper preservation and flavor extraction. Press down gently to remove air pockets.
Step 2: Add Aromatics and Liquid Base
Distribute the 4 cloves Garlic Cloves, 2 oz Fresh Ginger, and 2 whole Dried Chili Peppers evenly over the salted anchovies. These aromatics will infuse the sauce with their essence during fermentation.
Pour the 2 cups Water and 0.25 cup Rice Wine over the mixture until the anchovies are completely submerged. The liquid should cover everything by at least 1 inch. Add the 2 tbsp Sugar and stir gently to dissolve it in the brine.
Step 3: Begin the Fermentation Process
Cover the container loosely with a lid or clean cloth to allow airflow while keeping out debris. Store at room temperature, away from direct sunlight, for 1 week. You’ll notice the mixture becoming cloudy as the salt begins to break down the fish.
Stir the contents daily to ensure even fermentation and prevent mold growth on the surface. The anchovies will start to dissolve, and the liquid will take on a rich amber color. This active fermentation phase is crucial for developing the characteristic umami depth.
Step 4: Complete the Long Fermentation
After the initial week, seal the container tightly and move it to a cool, dark place. Let it ferment undisturbed for 6-12 months. The longer it sits, the more complex and mellow the flavor becomes.
Check occasionally to ensure the anchovies remain submerged. If the liquid level drops, add a small amount of water to cover. The sauce is ready when the anchovies have completely dissolved and the liquid has a deep, rich color with a powerful aromatic scent.
Step 5: Strain and Bottle the Finished Sauce
Line a fine-mesh strainer with cheesecloth and set it over a clean bowl or jar. Pour the fermented mixture through the strainer, allowing the liquid to drain completely. Avoid pressing on the solids, as this can make the sauce bitter.
Transfer the strained liquid to clean bottles or jars with tight-fitting lids. Store in a cool, dark place where it will keep for 1-2 years. The sauce will continue to mellow and develop complexity over time, becoming a versatile umami boost for countless dishes.
Pro Tips For Making Chinese Fish Sauce
- Use Fresh Anchovies: I learned this the hard way—stale or previously frozen anchovies make a dull, bitter sauce. Only use the freshest, never-been-frozen ones for clean, deep umami.
- Layer Salt Gradually: Don’t dump all the sea salt at once. Add it in 2-3 layers over the first week, stirring gently each time to avoid shocking the fermentation.
- Skip the Metal: Sounds weird, but it works: use glass or ceramic jars, never metal, which can react with the salt and rice wine and give your sauce a metallic tang.
- Stir Weekly, Not Daily: After the first week, stir just once a week—daily stirring breaks down the anchovies too fast and can make the sauce cloudy instead of rich and clear.
