Classic Homemade Sweet and Sour Sauce

Gather all of your ingredients needed for the sauce.

In a saucepan, combine ¾ cup of sugar, ⅓ cup of vinegar, ⅔ cup of water, ¼ cup of soy sauce, and 1 tablespoon of ketchup.

Set the saucepan over medium heat and stir until the sugar has fully dissolved.

Take your 2 tablespoons of cornstarch, dissolve it in a small amount of cold water, then pour it into the saucepan.

Stir the mixture continuously until it starts to thicken, then reduce the heat.

Let it simmer for about 5 additional minutes, or until it reaches your desired thickness. If it thickens too much, add a little bit of water and stir.

Let the sauce cool before using, or you can store it in the refrigerator for later use.
