This low histamine sweet and sour sauce blends natural sweetness from cane and coconut sugar with the sharp, fruity tang of apple cider vinegar for a bold but balanced flavor. Instead of soy sauce or traditional ketchup, use low histamine substitutes like coconut aminos and homemade tomato-free puree. This version is free from aged sauces and additives, making it friendly for those avoiding histamine triggers. It’s thick, glossy, and ready in just 5 minutes.
Ingredients Needed
- ½ cup + 2 tbsp organic cane sugar: adds balanced sweetness.
- 1–2 tbsp coconut sugar: adds a mild caramel flavor.
- ½ cup apple cider vinegar: tart base; if sensitive, use white distilled vinegar or omit.
- 3 tbsp coconut aminos: low histamine swap for tamari or soy sauce.
- ⅓ cup low histamine ketchup or tomato-free puree: avoid store-bought ketchup; use tomato-free, histamine-friendly version.
- 3–4 cloves garlic, minced: optional—can be reduced or replaced with garlic powder if sensitive.
- 2 tbsp water: helps dissolve starch.
- 1 tbsp arrowroot powder or cornstarch: thickener for glossy texture.
How To Make Low Histamine Sweet and Sour Sauce
Mix Main Ingredients:
In a small bowl, stir together cane sugar, coconut sugar, vinegar, coconut aminos, tomato-free puree, and garlic.
Bring to Boil:
Pour mixture into a small nonstick saucepan. Bring to a boil over medium-high heat. Let it bubble for 1–2 minutes, stirring often.
Thicken Sauce:
Whisk arrowroot powder with 2 tablespoons of water in a separate bowl. Pour into the saucepan, stirring constantly until the sauce thickens to your desired consistency.
Adjust as Needed:
If thicker sauce is desired, repeat with another tablespoon of arrowroot mixed with water. Or, chill in the fridge—it will thicken as it cools.
Use Immediately:
Serve warm over your favorite low histamine dish like tofu, chicken, or veggies.

Recipe Tips
- Use tomato-free puree: For lowest histamine, swap ketchup with a no-tomato veggie-based puree (like carrot, beet, or red bell pepper).
- Avoid aged soy sauce: Use coconut aminos for a gentle, soy-free option.
- Omit garlic if needed: Garlic can be a histamine trigger—adjust to your tolerance.
- Make a double batch: Freeze in silicone trays for quick meals later.
- Boil briefly: Longer cooking may concentrate histamine; quick cooking is best.
How to Store & Reheat
- Room Temperature: Let cool for up to 30 minutes only.
- Fridge: Store in a sealed container for 3–4 days.
- Freezer: Freeze in small containers or cubes for up to 2 months. Reheat gently on the stovetop.

FAQs
1. Can I use soy sauce in sweet and sour sauce?
No. Soy sauce is fermented and high in histamine. Coconut aminos is a safer, low histamine alternative.
2. What’s a good substitute for ketchup in low histamine diets?
Use tomato-free veggie purees like carrot, beet, or red bell pepper blends. Avoid store-bought ketchup due to preservatives and vinegar.
3. Is apple cider vinegar okay on a low histamine diet?
It’s tolerated by some, but others may react. Substitute with distilled white vinegar or skip if unsure.
4. How do I thicken sweet and sour sauce without cornstarch?
Arrowroot powder is a great low histamine thickener. Tapioca starch can also work.
5. Can I freeze this sauce?
Yes! Freeze immediately in small containers. Reheat gently to maintain a smooth texture.
