Which utensil is best suited for washing vegetables and fruits?

The best utensil for washing vegetables and fruits is a colander. A colander is specifically designed with perforations to allow water to drain while providing a surface to hold the produce. When washing fruits and vegetables, using a colander helps to rinse them thoroughly under running water while preventing any debris or dirt from getting trapped.

Additionally, the colander's shape allows for easy handling and thorough washing, as you can move it around to ensure even exposure to water. Other utensils mentioned are not suited for this task; a liquid measuring cup is intended for measuring liquids, a rubber spatula is used for mixing and scraping, and a whisk is designed for blending ingredients. Hence, their designs do not facilitate the effective washing of produce.
