Can you substitute icing sugar for fruit sugar?

Icing sugar and fruit sugar (often referring to fruit-derived sugars like fructose or fruit juice concentrates) are not direct substitutes due to their different compositions and uses. Icing sugar is a finely powdered form of sucrose, ideal for frosting and baking, while fruit sugar can affect flavor and moisture content. If you're looking for a sweetener to use in a recipe, consider the intended flavor and texture, as well as how each sugar interacts with other ingredients.
