Common Mistakes to Avoid
- Skipping the cornstarch slurry. Sauce will be too runny without it.
- Overheating garlic. Burnt garlic = bitter sauce. Keep it gentle.
- Not adjusting chili. Heat varies—taste before bottling.
- Adding cornstarch too fast. Slowly stir in to avoid lumps.
- Ignoring the balance. Sweet, sour, and spicy should all be present.
Alternatives & Substitutions
- No rice vinegar? Use white vinegar or apple cider vinegar.
- Want it thicker? Add a touch more cornstarch slurry.
- Prefer less heat? Reduce chili flakes or swap with paprika for mild flavor.
- Want more flavor? Add a splash of soy sauce for umami.
- Sugar-free option? Use honey or maple syrup, adjusting water as needed.
