Blend, or mix, refers to the process of combining two or more substances to create a uniform mixture. This can occur in various contexts, such as cooking, where ingredients like fruits and vegetables are blended to make smoothies, or in art, where different paints are mixed to achieve new colors. In science, blending can involve combining liquids or solids, such as when chemicals are mixed to create a reaction. The goal of blending is often to achieve a consistent texture or flavor, making it an essential technique in many fields, including culinary arts, manufacturing, and cosmetics.
