Pro Tips for Perfect Sweet and Sour Sauce
Color expectations: Don't expect a bright red color without food coloring. The natural color will be more of a reddish-brown, but the flavor will be superior.
Safety first: Be cautious when cooking with sugar mixtures, as they can cause severe burns if they splash on skin. Also, avoid directly inhaling vinegar fumes while cooking.
Consistency control: For a thicker sauce (ideal for coating chicken or shrimp), add a bit more cornstarch. For a thinner dipping sauce, reduce the cornstarch slightly.
Flavor balance: Taste as you go! The perfect sweet and sour sauce should have a balance where neither the sweetness nor the tanginess overwhelms the other.
Quality ingredients: Use a good-quality ketchup that isn't overly sweet, since you're adding plenty of sugar to the recipe.
