Chinese Sweet and Sour Sauce

It may seem like a mystery, you know, how to make sweet-and-sour sauce. But I promise it is very easy to do. You may even have the ingredients on hand if you want to make your homemade sauce.

One of the things I like most about recreating restaurant favorites is knowing exactly what you put in your food. I know when you try this sauce, you will be amazed at how much better it tastes than what you can buy in a jar.

What Makes this Sauce so Good

Unlike many other online recipes, this one includes actual fruits. Most contain very similar ingredients. They include ketchup, yes, you read that right, sugar, vinegar, and water.

This version has a more complex flavor because we are going to flavor our water with fresh oranges, lemons, and ginger. I think the natural fruit juice and oils extracted from the water make a significant difference in the final flavor.

CopyKat Chef’s Notes

• Citrus Balance: Fresh orange and lemon create the bright flavor that gives this sauce its signature sweet-tart taste. If the sauce tastes too sharp, add a small amount of sugar to round out the acidity.

• Color Control: Ketchup provides both sweetness and the familiar red color seen in many restaurant sweet and sour sauces. Adjust the amount slightly if you want a deeper color or a milder tomato flavor.

• Thickness Control: The cornstarch slurry thickens the sauce quickly, so add it gradually while stirring. If the sauce becomes too thick, whisk in a tablespoon of water until it reaches the desired consistency.

• Smooth Texture: Strain the sauce after simmering the citrus and ginger if you prefer a completely smooth dipping sauce. Leaving it unstrained will give the sauce a more rustic texture and stronger citrus flavor.

• Flavor Development: Let the sauce cool slightly before serving so the citrus, sugar, and vinegar flavors have time to meld and balance.

Storage & Reheating Instructions

• Refrigerator Storage: Store sweet and sour sauce in an airtight container in the refrigerator for up to 1 week. Stir before using if the sauce settles slightly.

• Reheating Method: Reheat gently in a small saucepan over low heat, stirring occasionally until warm. If the sauce becomes too thick, add a small splash of water to loosen it.

• Freezing: Freeze the sauce in a freezer-safe container for up to 2 months. Thaw overnight in the refrigerator and reheat gently on the stovetop while stirring.

  1. Hi Stephanie! Do you have a recipe for Leann Chins dipping sauce? What you get with wontons. Like pineapple something…. Thank you!

  2. Thank you a lot for this amazing sauce. I just it. It tastes pretty good like take away restaurants. The only issue that remained is the bitterness of the sauce that is due to the lemon and orange. How can I eliminate bitterness? Thank you!

  3. Hi Stephanie,

    First off thank you for all of your hard work and contributions to this site! You are appreciated! My questions as it pertains to this recipe, when you say “slice the fruit and slice ginger” how exactly are you slicing it? Thank you in advance!

    Best,
