What kitchen tool can be used to level off ingredients in a measuring cup?

Using a rubber spatula to level off ingredients in a measuring cup is an effective technique in cooking and baking. The flexible edge of a rubber spatula allows it to easily slide across the top of the measuring cup, ensuring that the ingredient is even with the rim. This is particularly important for dry ingredients like flour or sugar, where precise measurements can significantly impact the final result of a recipe.

The other tools listed—such as a ladle, whisk, and slotted spoon—serve different culinary purposes. A ladle is designed for serving liquids, a whisk is used for blending or incorporating air into ingredients, and a slotted spoon is typically employed for lifting food from liquids without transferring the liquid itself. None of these tools are designed to provide the accuracy and precision needed to level off ingredients in a measuring cup like a rubber spatula does.
