A sweet and sour dip is a tangy and flavorful sauce made from a blend of sweet ingredients like sugar or honey and sour elements like vinegar or citrus juice. It's typically enhanced with garlic, soy sauce, and sometimes a hint of chili for spice. This dip is perfect for pairing with appetizers like spring rolls, chicken nuggets, or fried wontons, offering a balance of sweetness and acidity that enhances the flavors of the dish.
