Ingredients

• 3 tablespoons fermented black beans (rinsed and roughly chopped)
• 2 tablespoons vegetable oil (or any neutral cooking oil)
• 4 cloves garlic (minced)
• 1 tablespoon ginger (fresh, grated)
• 2 tablespoons soy sauce (or tamari for gluten-free)
• 1 tablespoon dark soy sauce (for color and added depth)
• 1 tablespoon brown sugar
• 1 teaspoon chili flakes (optional, for a spicy kick)
• 1/2 cup vegetable broth (or water)
• 1 teaspoon cornstarch (mixed with 2 teaspoons water to thicken)
• 2 green onions (thinly sliced, for garnish)

Equipment

• Small bowl (for soaking and rinsing fermented black beans)
• Knife and cutting board
• Grater or microplane (for ginger)
• Wok or large skillet
• Wooden spoon or spatula
• Measuring spoons and cups
• Small whisk or fork (for cornstarch slurry)

Instructions

1. Prep the black beans: Place the fermented black beans in a small bowl and rinse under cold water to reduce saltiness. Drain well and roughly chop to release more flavor.
2. Heat the oil: In your wok or skillet, warm the vegetable oil over medium heat until shimmering.
3. Sauté aromatics: Add the minced garlic and grated ginger. Stir-fry for about 1 minute until fragrant, being careful not to burn them.
4. Add black beans: Stir in the chopped fermented black beans and cook for another 1-2 minutes. This helps bloom their flavor in the oil.
5. Mix in sauces and sugar: Pour in the soy sauce, dark soy sauce, and sprinkle the brown sugar. Stir well to combine all ingredients evenly.
6. Add broth and simmer: Pour in the vegetable broth, stirring to deglaze the pan. Allow the sauce to simmer gently for 3-4 minutes.
7. Thicken the sauce: Stir the cornstarch slurry to recombine, then slowly pour it into the sauce while stirring continuously. Cook for 1-2 minutes until the sauce thickens to a glossy consistency.
8. Optional spice: If you prefer heat, sprinkle in chili flakes and stir to incorporate.
9. Finish and garnish: Remove from heat and stir in half of the sliced green onions. Save the rest for garnish when serving.

Tips & Variations

“Rinsing the fermented black beans is key to balancing their saltiness and bitterness.”

Use fresh fermented black beans if you can find them at an Asian grocery store—they’re the heart of this sauce.

For a smoky twist, add a dash of toasted sesame oil at the end of cooking. You can also customize the heat level by adjusting or omitting the chili flakes.

If you want a thicker, chunkier sauce, add chopped mushrooms or minced bell peppers along with the black beans.

To make this sauce nut-free and soy-free, substitute soy sauce with coconut aminos.
