This recipe expertly replicates McDonald's iconic sweet and sour sauce, combining apricot and peach preserves with corn syrup, vinegar, and savory spices. It's a versatile, balanced condiment, perfect for dipping chicken nuggets, spring rolls, or elevating various Asian-inspired dishes with its signature sweet, tangy, and savory profile.
To achieve a perfectly smooth sauce, always dissolve the cornstarch in cold water first to create a slurry before adding it to the hot mixture; this prevents lumps. Use a non-reactive saucepan to avoid any metallic off-flavors interacting with the acidic vinegar. Simmer gently until the sauce coats the back of a spoon, keeping in mind it will thicken further as it cools. For optimal flavor melding, prepare the sauce in advance and chill it thoroughly. Store in an airtight container in the refrigerator for up to a week.
