Ingredients
  

  • 1/2 cup low-sodium soy sauce (or tamari for gluten-free)
  • 3 tablespoons brown sugar (light or dark)
  • 2 tablespoons honey (or maple syrup)
  • 2 tablespoons rice vinegar (or apple cider vinegar)
  • 1 tablespoon gochujang (Korean chili paste; adjust to taste)
  • 1 teaspoon gochugaru (Korean chili flakes; optional for extra heat)
  • 2 tablespoons mirin (optional, adds mild sweetness and depth)
  • 2 teaspoons toasted sesame oil
  • 4 cloves garlic, finely grated or minced
  • 1 tablespoon fresh ginger, finely grated
  • 1/3 cup water
  • 2 teaspoons cornstarch mixed with 2 teaspoons cold water (slurry)
  • 1 tablespoon finely sliced green onions (optional, for finish)
  • 1 teaspoon toasted sesame seeds (optional, for finish)

Method
 

  1. Set up a heat-safe dish: Choose a small, oven-safe bowl or shallow baking dish that fits in your air fryer. This will hold the sauce. Line the air fryer basket with foil under the dish if drips are a concern.
  2. Combine the base: In the dish, whisk together soy sauce, brown sugar, honey, rice vinegar, gochujang, gochugaru (if using), mirin, sesame oil, garlic, ginger, and water until smooth.
  3. Preheat the air fryer: Heat to 300°F (150°C). This moderate temperature helps thicken the sauce without scorching the sugars.
  4. Cook the sauce: Place the dish in the air fryer and cook for 6–8 minutes. Carefully open and stir once halfway through. You should see gentle bubbling around the edges.
  5. Thicken with slurry: Stir the cornstarch slurry to recombine, then whisk it into the sauce. Return to the air fryer for 2–4 minutes, stirring once, until glossy and slightly thickened. The sauce will thicken more as it cools.
  6. Taste and adjust: For more sweetness, add a bit more honey. For more heat, add a pinch of gochugaru. For more tang, add a splash of rice vinegar.
  7. Finish and cool: Remove from the air fryer. Stir in green onions and sesame seeds if you like. Let the sauce cool for 10–15 minutes; it will set to a perfect glaze-like consistency.
  8. Use it your way: Brush over air-fried chicken thighs, tofu cubes, salmon, mushrooms, or cauliflower in the last 2–3 minutes of cooking to caramelize. Or use as a dipping sauce for dumplings or crispy wings.
