Why I Like This Recipe
Honestly? I was just looking for something to dip frozen egg rolls into. Didn’t wanna open a bottle. Tossed this together while my air fryer ran and it ended up hitting way better than expected. Plus now I just keep a jar in the fridge. No regrets.
Ingredients
- ¾ cup white sugar
- ⅔ cup water
- ⅓ cup white vinegar
- ¼ cup soy sauce
- 2 Tbsp cornstarch
- 1 Tbsp ketchup
How To Make Sweet And Sour Sauce
- Combine it all: Toss everything—yes, all of it—into a medium saucepan. No fancy order. Just dump and stir.
- Heat things up: Bring it to a boil over medium heat. Keep stirring. It’ll look weird at first but just wait.
- Let it thicken: After a couple minutes bubbling, it’ll start to thicken. That’s the cornstarch doing its thing. Stir a bit more till it gets glossy.
- Cool it down: Take it off the heat. It thickens even more as it cools.
- Use or store: Serve warm if you’re using right away. Otherwise let it cool and pour into a jar. Fridge lfe is solid for at least a week.

Tips for Success
- Stir constantly once it starts to boil. No one likes lumpy sauce.
- Use white vinegar—it’s the classic tang. Apple cider gives it a totally different vibe.
- Taste before storing. If it’s too tart, add a bit more sugar next time.
- Don’t skip the ketchup—it pulls it all together, weirdly.
Storage and Reheating
- Fridge: Sealed in a jar = good for 5–7 days.
- Microwave: Reheat in 10-second bursts, stir between.
- Stovetop: Low heat, small pan, stir it gently. That’s all it takes.
Frequently Asked Questions
- Can I use brown sugar instead?
You can—it’ll taste a little richer. Different vibe, still good. - What if I don’t have cornstarch?
Arrowroot or tapioca starch can work. Flour… not ideal. - Can I double the recipe?
Yep. Just make sure your pot’s big enough. It bubbles up fast. - Why is my sauce too runny?
You probably didn’t simmer it long enough. Give it a minute more next time. - Can I freeze it?
Technically yes, but it gets weird when thawed. Better to make fresh.
Common Mistakes and How to Dodge Them
- Not stirring while boiling: That starch sinks fast. Stir or you’ll get globs.
- Using too much vinegar: Stick to the recipe the first time. It’s balanced as-is.
- Overcooking: If it gets too thick, it’s hard to fix. Pull it off heat once it coats a spoon.
- Swapping vinegar types randomly: White vinegar keeps it classic. Rice vinegar = sweeter. Balsamic? Just don’t.
- Forgetting to taste it: You might want a bit more tang or sweet, depending on your soy sauce brand. Taste, then store.
