Honey (Best Option)
3/4 cup honey per 1 cup granulated sugarHoney is a natural sweetener composed mainly of fructose and glucose, which dissolve readily in liquids, making it ideal for soups. Its enzymatic and antioxidant properties can also enhance flavor complexity.
When substituting, reduce other liquids slightly to account for honey's moisture content and add honey towards the end of cooking to preserve its delicate flavors. Avoid overheating to prevent bitterness.
Compared to granulated sugar, honey imparts a richer, more complex sweetness and slightly thickens the soup, which can enhance mouthfeel without making it syrupy.
