In a medium saucepan over medium heat, combine the orange juice, orange zest, grated ginger, minced garlic, soy sauce, honey, rice vinegar, and crushed red pepper.
Stir and allow the mixture to simmer gently for about 5-7 minutes. Stir occasionally.
Mix cornstarch with water in a small bowl until smooth.
Gradually stir this slurry into the simmering sauce.
Cook for another 2 minutes, or until the sauce achieves your desired thickness.
Use as a glaze or as a dip.
Notes
If using dark soy sauce, reduce the quantity by half to avoid overpowering flavors.
For a vegan version, swap honey with maple syrup or brown sugar.
Adjust the heat to your liking: reduce or skip the red pepper flakes for a mild flavor, or add Thai chilies for a more intense kick.
This sauce doubles as a marinade or salad dressing—perfect for grilled meats, meatballs, or stir-fries.
Store in the fridge for 3 days or freeze up to 2 months; reheat gently before serving.
