Root vegetables, like potatoes and carrots, should be scrubbed with a brush under running water to remove dirt, while leafy vegetables, like lettuce and spinach, should be gently swished in a bowl of cold water to avoid bruising.
The primary difference in washing root vegetables versus leafy vegetables stems from their structure and the type of contaminants they typically carry. Root vegetables grow underground and are therefore covered in soil, which can be difficult to remove. Leafy vegetables, on the other hand, are more delicate and prone to damage, and they primarily collect surface-level dirt and debris.
Here's a breakdown of how to wash each type:
Don't wash leafy greens until you're ready to use them. Washing them ahead of time and storing them wet can lead to faster spoilage. Store washed and dried greens in a container lined with paper towels to absorb excess moisture.
