How to Make Sweet and Sour Sauce
Step 1: Combine Initial Ingredients
In a small saucepan, add the sugar, vinegar, and ⅔ cup of water. Place over medium heat. Whisk constantly until the sugar completely dissolves into the mixture.
Step 2: Add Ketchup
Once the sugar is melted, add the ketchup to the saucepan. Continue to whisk the mixture until everything is well combined and smooth.
Step 3: Prepare the Cornstarch Slurry
In a small bowl, mix together the cornstarch and 2 tablespoons of water. Stir until smooth, forming your slurry.
Step 4: Thicken the Sauce
Bring the vinegar mixture to a gentle boil. Slowly stream in the cornstarch slurry while whisking continually. Keep whisking until the sauce thickens to your desired consistency, which should take about 30 seconds.
Step 5: Cool and Serve
Once thickened, remove the saucepan from heat. Let the sauce cool before using, or serve immediately while warm.

Pro Tips from My Kitchen
✓ Adjust the Sweetness – If you prefer a sweeter sauce, feel free to add a bit more sugar or ketchup. Taste as you go to get your ideal flavor.
✓ Use Low-Sodium Soy Sauce – For a richer flavor, add a splash of low-sodium soy sauce to the mixture. It enhances the savory notes without overpowering the sweetness.
✓ Store Properly – Keep leftover sauce in an airtight container in the fridge. It should last about a week, making it convenient for future meals.
✓ Watch the Heat – Do not rush the heating process. Whisking well ensures the sugar dissolves before boiling, which prevents any grainy texture.
✓ Experiment with Spices – Add a pinch of garlic powder or crushed red pepper for an extra kick. These spices can deepen the flavor profile of your sauce.
