Recipe Information
Ingredients
- 1 medium (finely diced) Yellow onion
- 0.5 cup Soy sauce (low sodium or gluten-free tamari for gluten-free option)
- 3 tablespoons Erythritol or monk fruit sweetener
- 2 tablespoons Apple cider vinegar
- 2 cloves (minced) Garlic
- 1 teaspoon (grated) Fresh ginger
- 0.5 cup Water
- 0.25 teaspoon Xanthan gum (for thickening)
- 1 teaspoon Sesame oil
- 1 teaspoon Toasted sesame seeds (optional, for garnish)
Instructions
1. Heat the sesame oil in a small saucepan over medium heat.
2. Add the finely diced onion and sauté for 5-7 minutes until the onion is softened and caramelized, stirring frequently to avoid burning.
3. Add the minced garlic and grated ginger to the saucepan, cooking for 1 minute until fragrant.
4. Stir in the soy sauce (or tamari), erythritol or monk fruit sweetener, apple cider vinegar, and water. Mix well to combine all the ingredients.
5. Allow the mixture to come to a gentle simmer, then reduce the heat to low and let it simmer for 5-7 minutes. Stir occasionally to prevent sticking.
6. Gradually sprinkle the xanthan gum into the sauce while continuously whisking to avoid clumps. Continue cooking for another 1-2 minutes until the sauce thickens to your desired consistency.
7. Taste the sauce and adjust sweetness or saltiness as needed by adding more erythritol or soy sauce.
8. Remove the saucepan from heat and let the sauce cool slightly. Transfer to a clean, airtight container if not using immediately.
9. If desired, garnish the sauce with a sprinkle of toasted sesame seeds before serving.
10. Use as a marinade, dipping sauce, or stir-fry sauce. Store any leftovers in the refrigerator for up to 1 week.
