The running water method is a great way to clean lettuce, but it's not practical for washing whole cases of produce. Use this method when you need to prep one head of lettuce or a few leaves. Remove any portions of the head that have been cut or damaged. Bacteria can get inside lettuce leaves that have been damaged.
Fill a large bowl with cold water. Remove any damaged outer leaves and use a chef's knife to trim off the stem end of the lettuce, if present. Separate the leaves, drop them into the bowl of water, and using clean hands, swirl them around the bowl to dislodge any dirt or sand.
The Rule is: Lettuce is washed in cold Water!
Pluck lettuce and wash it quite quickly in cold water, change the water several times if it is very dirty. The process should be completed in a maximum of 10 minutes.
Before washing heads of lettuce, remove any damaged outer leaves and cut off the stem ends. 3. Wash the leaves in the water. Separate the leaves, drop them into the water, and swish them around with your hands.
Proper air circulation and a small amount of moisture will keep your lettuce crisp and fresh. The easiest (and most effective) way to do this is to line a sturdy glass or plastic container with a few paper towels, then scatter your greens on top. Top with a matching lid and refrigerate.
Washing leafy greens does not remove all germs. That's because germs can stick to the surface of leaves and even get inside them. If you eat contaminated leafy greens without cooking them first, such as in a salad or on a sandwich, you might get sick.
Place a clean dish towel or paper towels over a rimmed baking sheet (or just right on your table). Spread the leaves over the towel and let them air dry for about half an hour or or so. That's it. If they're extra wet, you can blot them a bit with another towel before leaving them to air dry.
A salad spinner will clean greens better than handwashing (by making sure to actually remove the dirty water, instead of letting it sit on the leaves) and with less mess and hassle. It will also dry your greens more efficiently, and the less water you have on your lettuce, the better your vinaigrette will stick.
Drying Method: Laid Out on Paper Towels
About this method: This method is just what it sounds like. Lay down some paper towels in a sheet pan and sprinkle wet lettuces on top. You will need to occasionally toss the greens to make sure the water doesn't pool and that it dries evenly.
Indeed, many (though not all) food safety specialists advise against washing bagged lettuce or spinach. Why? First, because there's a good chance that if bacteria managed to survive commercial-scale washing with chlorinated water in the processing plant, a lot of them will survive your home washing, too.
You can wash your lettuce before or after storing it in the refrigerator. If you wash the lettuce before storage, place a paper towel in the plastic bag or reusable container, which can absorb excess moisture, preventing your lettuce from turning soggy and extending the shelf life.
Is It Better to Store Lettuce Washed or Unwashed? Head lettuce, such as iceberg and romaine, keeps fresh longer when it remains attached to the head and unwashed. Rinse the leaves only when you are ready to use them.
Adding vinegar to the water (1/2 cup distilled white vinegar per 1 cup water), followed by a clean water rinse, has been shown to reduce bacterial contamination but may affect texture and taste. After washing, blot dry with paper towels or use a salad spinner to remove excess moisture.
Fill a large bowl with very hot tap water (around 120°F) and plunge your wilted greens. Let them soak for 10–30 minutes, then drain. Wrap the leaves in a damp towel and chill before using (or if you need them immediately, cool them down in ice water). They'll be perkier than a Pomeranian with a plushie.
All produce, from leafy greens or fresh herbs to firm fruits and veggies, should be washed before eating. Use baking soda and cold water when washing produce to help remove chemical residue and dirt.
