Fill a large bowl or a clean sink with plenty of cool water. Add the lettuce or greens and swish them around to loosen and remove any dirt. Dirt and debris will sink to the bottom while the greens will magically float above all that mess.
At home, just fill a large bowl or your kitchen sink. Separate the greens and add them to that large quantity of cold water. Vigorously swirl the water and agitate the greens. You want the moving water to shake the dirt out of the nooks and crannies in the leaves.
Yes, it's important to wash all fresh produce, but especially leafy greens and lettuce. Harmful bacteria from the soil can contaminate fruits and vegetables and lead to a foodborne illness if consumed. There's a higher risk associated with produce that is eaten raw, like romaine lettuce and salad greens.
Wash all leafy green vegetables, including pre-bagged greens under cold running tap water. For leafy vegetables, such as lettuce and cabbage, remove the outer leaves first. Throw away any wilted or discoloured leaves.
CDC estimates that germs on produce eaten raw cause a large percentage of U.S. foodborne illnesses. Leafy greens and other vegetable row crops are a major source of E. coli O157 infections. Other harmful germs found on leafy greens include norovirus, Salmonella, Listeria, and Cyclospora.
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.
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.
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.
Clean fresh produce.
For extra protection, adding one part vinegar or lemon juice to the three parts water helps, but you don't need to use any soap, detergents or special cleaners. It is important to rinse food even if you are going to peel it. - Use a scrub brush to remove additional dirt and bacteria.
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.
Washing lettuce in water (or water combined with baking soda) may help remove pesticide residue, surface dirt and debris from produce, but Rogers cautions that washing has not been proven an effective way to remove E. coli and related bacteria.
They Use Perforated Container
The use of perforated bins is the key to keeping lettuce fresh and crisp at all times. Restaurants keep them in perforated containers to allow air circulation in the refrigerator. To keep its crispness, lettuce requires air and a small amount of moisture.
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.
Put into an airtight container submerged in water. Remove leaves when needed or use entire lettuce. You can change water every three days so lettuce lasts longer. Lettuce stays fresh anywhere from ten days to a whole month!
Lettuce wilts because it loses water, so the key to reviving it is to put the water back in. We've had success simply soaking the wilted leaves in ice water for 30 minutes.
