65 Sauce Recipe: Fiery Fermented Condiment for Bold Flavors

This fermented condiment delivers an intense fiery kick with complex umami depth that elevates any dish.

With just a few simple ingredients and patience, you’ll create a bold sauce that transforms meals with its tangy, spicy character.

Ingredients for 65 Sauce

Nine ingredients come together to create a sauce with serious heat and depth.

The chili peppers are non-negotiable for authentic heat—look for fresh red Thai bird’s eye or serrano peppers at Asian markets or well-stocked grocery stores. Choose firm, glossy peppers with no soft spots. The fish sauce should be Vietnamese (like Red Boat or Three Crabs) for the right umami balance. Avoid brands with added preservatives or MSG.

No fresh chilies? Dried bird’s eye chilies rehydrated in warm water work in a pinch, but reduce by one-third since dried are more concentrated. Swap shallots for yellow onion if needed—flavor will be milder. For a vegetarian twist, soy sauce or tamari replaces fish sauce, though the profile changes slightly. The sugar can be palm sugar for a deeper molasses note.

This sauce ferments for 7-10 days at room temperature, developing complexity over time. Store in a glass jar in the fridge for up to 6 months once fermented. The flavors continue to meld, so it’s worth making a big batch.

Step-by-Step Instructions for Fiery Fermented Condiment

This method ensures proper fermentation and balanced flavors in your homemade condiment.

Step 1: Prepare the Aromatics and Chilies

Begin by thoroughly washing and drying the 20 whole Red Chili Peppers. Remove stems and slice them into thin rings, keeping the seeds for heat. Peel and finely chop the 0.5 cup Shallots, then peel and slice the 2 whole Ginger Root into thin coins.

Peel and smash the 8 cloves Garlic Cloves with the flat side of your knife—this releases more flavor than mincing. Combine all these ingredients in a clean glass jar. The fresh, pungent aroma of smashed garlic and sliced ginger will intensify during fermentation.

Step 2: Create the Brine Solution

In a saucepan, combine the 1 cup White Vinegar, 0.5 cup Granulated Sugar, and 1 tbsp Salt. Heat over medium heat until the sugar and salt fully dissolve, creating a clear brine. This typically takes 3-4 minutes of gentle stirring.

Remove from heat and let cool to room temperature. Adding hot brine to your jar could compromise the fermentation process and dull the vibrant colors of your chilies. The brine should taste balanced—salty with a touch of sweetness.

Step 3: Combine All Ingredients

Pour the cooled brine over the chili mixture in your jar. Add the 0.5 cup Fish Sauce and 0.25 cup Lime Juice. The Vietnamese fish sauce adds depth, while the lime juice contributes brightness to cut through the heat.

Stir gently with a clean spoon to ensure all ingredients are fully submerged in the liquid. You should see the red chilies, pale shallots, and golden ginger pieces suspended in the tangy, slightly cloudy brine. Press down lightly to remove any air bubbles.

Step 4: Ferment and Store

Seal the jar tightly and store it at room temperature, away from direct sunlight. During the first 2-3 days, you’ll notice the colors deepen as the flavors meld. The liquid may become slightly cloudy as fermentation begins.

After 7 days, transfer the jar to the refrigerator to slow the fermentation. The condiment will continue to develop complexity for up to 4 weeks, but can be used after the initial week. The ideal flavor profile emerges when the heat from the chilies balances with the tangy, umami-rich base.

Always use clean utensils when removing portions to prevent contamination. The sauce should have a vibrant red color with visible chili flakes and aromatic pieces throughout.

Dietary Considerations for These Flavors

Gluten-Free Naturally

This creation contains no gluten ingredients, making it safe for anyone with celiac disease or gluten sensitivity. All components—from Red Chili Peppers to Fish Sauce—are naturally gluten-free. Just verify your fish sauce brand, as some contain wheat.

Vegan Adaptation

To make this vegan, simply swap fish sauce for soy sauce or tamari. The umami depth will shift slightly but remain delicious. Three Crabs and Red Boat make vegan fish sauce alternatives that work perfectly. 💪

Low-Sodium Option

Reduce salt to ½ tbsp and use low-sodium fish sauce. The fermentation process enhances flavors naturally, so you won’t miss the extra salt. Taste before adjusting—you might find the reduced sodium version just as satisfying.

Sugar-Free Version

Replace granulated sugar with erythritol or monk fruit sweetener. The fermentation still works, though the color may be slightly lighter. I’ve found Swerve brand dissolves beautifully in the brine.

Allergen Note

This condiment contains no dairy, eggs, nuts, or soy (unless using soy sauce as a fish sauce substitute). It’s naturally free from most common allergens. Always check labels on your fish sauce for hidden allergens.

Calorie Conscious

Each tablespoon contains about 10-15 calories, mostly from the natural sugars. The heat from the chilies may even boost metabolism slightly. I use this to add flavor without significant calories. 💡
