📝 About This Recipe

Capture the soul of the famous 'Rooster Sauce' with this elevated, home-fermented version that balances fiery heat with a sophisticated tang. Unlike store-bought varieties, this recipe utilizes a 5-day fermentation process to develop deep, complex probiotic flavors and a vibrant ruby hue. It is a harmonious blend of sun-ripened red jalapeños, pungent garlic, and a touch of sweetness that creates a versatile condiment perfect for drizzling over everything from avocado toast to spicy noodles.

🥗 Ingredients

The Chili Base

  • 1.5 pounds Red Jalapeño Peppers (stems removed, kept whole)
  • 1/2 pound Red Fresno Chilies (for added brightness and heat)
  • 6-8 pieces Garlic Cloves (peeled and smashed)

The Fermentation & Seasoning

  • 4 tablespoons Light Brown Sugar (packed)
  • 1 tablespoon Kosher Salt (do not use iodized salt)
  • 1/2 cup Distilled White Vinegar (high quality)
  • 1/4 cup Rice Vinegar (for a mellow acidity)
  • 2 tablespoons Water (filtered)

👨‍🍳 Instructions

  1. 1

    Thoroughly wash the red jalapeños and Fresno chilies. Remove the green stems but keep the seeds intact, as they provide the signature heat of the sauce.

  2. 2

    In a high-powered blender or food processor, combine the peppers, garlic cloves, brown sugar, and kosher salt. Pulse until the mixture forms a coarse, uniform paste.

  3. 3

    Transfer the chili paste into a clean, sterilized half-gallon glass jar. Ensure there is plenty of headspace at the top, as the mixture will bubble and expand during fermentation.

  4. 4

    Wipe down the inside edges of the jar. Cover the jar loosely with plastic wrap secured by a rubber band, or use a fermentation lid with an airlock.

  5. 5

    Place the jar in a cool, dark spot in your kitchen. Let it sit for 3 to 5 days. Once a day, remove the cover and stir the paste with a clean spoon to submerge any solids and check for tiny bubbles—the sign of active fermentation.

  6. 6

    Once the mixture smells pleasantly tangy and has developed a slightly darker red color (usually by day 5), pour the fermented paste back into the blender.

  7. 7

    Add the distilled white vinegar and rice vinegar to the blender. Puree on high speed for 2-3 minutes until the sauce is as smooth as possible.

  8. 8

    Place a fine-mesh strainer over a medium saucepan. Pour the puree into the strainer and use a silicone spatula to push the liquid through, discarding the remaining seeds and pulp for a silky texture.

  9. 9

    Bring the strained sauce to a boil over medium-high heat. Once boiling, reduce the heat to low and simmer for 10-15 minutes.

  10. 10

    As the sauce simmers, it will thicken and the flavors will concentrate. Skim off any foam that rises to the surface.

  11. 11

    Remove from heat and let the Sriracha cool completely to room temperature. It will continue to thicken slightly as it cools.

  12. 12

    Transfer the finished sauce to sterilized glass bottles or jars. Store in the refrigerator for up to 6 months.

💡 Chef's Tips

Wear gloves when handling large quantities of hot peppers to avoid skin irritation. If you prefer a thicker sauce, simmer for an additional 5-10 minutes during the final cooking stage. Always use non-iodized salt, as iodine can inhibit the growth of beneficial bacteria during fermentation. If your sauce is too spicy, add an extra tablespoon of sugar; if it's too thick, whisk in a splash of water or vinegar.

🍽️ Serving Suggestions

Drizzle over a steaming bowl of Phở or spicy Ramen for an authentic kick. Mix with high-quality mayonnaise to create a creamy 'Sriracha Mayo' for sushi rolls or burgers. Use as a bold dipping sauce for crispy spring rolls or fried calamari. Stir a spoonful into scrambled eggs or over a breakfast burrito to start your day with heat. Combine with honey and lime juice to create a spicy glaze for grilled chicken wings.
