How should leafy greens be prepared before washing?

Leafy greens should be pulled apart completely before washing to ensure that all surfaces are exposed to water and any contaminants can be effectively removed. This process allows water to reach between the leaves, where dirt, pesticides, or bacteria might be lodged. Thorough washing of leafy greens is crucial in food safety, as improper cleaning can lead to foodborne illnesses.

Leaving the leaves intact can create hiding spots for dirt and pathogens that won't get washed away efficiently. Chopping them into small pieces before washing may also trap contaminants inside the cut surfaces, making it difficult to achieve a thorough clean. Running leafy greens through a blender is not a method of washing; it does not appropriately sanitize or clean the greens and can damage them further. Hence, completely pulling apart the leaves is the most effective way to prepare them for washing.
