How to clean romaine lettuce

The answer: It’s probably fine, but to be safe, wash (or re-wash) all lettuce before using it in your salad, whether it’s straight from the garden or the supermarket shelf. Don’t worry, washing and drying lettuce doesn’t take as long as you might think if you have the right tools in place.

Submerge the lettuce in a bowl of ice water for about 30 minutes to refresh and crisp it again. Spin to dry before eating.

Using a solution that’s three parts water and one part vinegar will be most effective at removing bacteria. Using vinegar, however, is not necessary because simply washing fruits and vegetables with clean water will remove 98 percent of bacteria.

Health experts actually advise against washing bagged salad

While there is some level of risk, the U.S. Food and medicine Administration says greens which are labelled “triple-washed” or “ready-to-eat” can be eaten without being washed after they are taken out of the bag.

Pre Bagged Salads Are The Most Dangerous

Salads can contain bugs that cause food poisoning including E coli, salmonella and norovirus. Some do make their own from whole leaves, but if it’s a fast, convenience food or a chain then it’s often straight out of a bag.

Additional washing of ready-to-eat leafy green salads is not likely to increase safety. The risk of cross-contamination from food handlers and food contact surfaces used during washing may outweigh any safety benefit that further washing may do.

Many of the big producers (like Dole), explains Farber, use water along with disinfectants such as chlorine, to clean their bagged and packaged (as long as it’s labelled pre-washed!)

According to The Guardian, researchers at the University of Leicester in England discovered that the juices released from the broken leaves of lettuce, spinach, and other greens increase the risk of the bacteria salmonella 2,400-fold.

There are two main risks of eating unwashed fruits and vegetables: bacterial contamination and pesticides. coli) infections from contaminated romaine lettuce.

Use food-grade hydrogen peroxide for 10 min

To use hydrogen peroxide as a cleaning agent, mix 1 tablespoon of hydrogen peroxide to 3 liters of water. Soak the lettuce completely in the hydrogen peroxide solution and let it sit for 10 minutes. After 10 minutes, rinse everything off with cold water.

Vinegar doesn’t work well as a disinfectant. According to EPA standards, a disinfectant should be able to eliminate 99.9 percent of disease-causing bacteria and viruses. Vinegar only works against some germs, like E. coli and Salmonella.

Adding Salmonella or E. coli cocktails to undiluted vinegar or juice showed white vinegar was the most lethal. Treating inoculated lettuce with straight or diluted white vinegar (5% or 2.5% acetic acid) for 60 seconds resulted in a 2-3 Log₁₀ reduction of Salmonella, E. coli, and coliforms.

The easiest way to clean your greens is to agitate and soak them in a large quantity of water. At the restaurant, that meant filling 10-gallon sinks with cold water to soak 20 heads of lettuce at a time. At home, just fill a large bowl or your kitchen sink.

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.

Washing Method: Clean Sink

For this method, fill a clean sink with cold water, then add a colander with greens to the basin. Then agitate, rest, agitate again, and then rest before pulling up the colander to allow the excess water and dirt to drain out. I transferred the colander to a plate to catch any excess water.

Drain and rinse the head again with plain cold water. Finally, drain the lettuce on paper towels or a clean dry towel. Pat the head dry and then refrigerate it in a bowl with a lid. In about one hour, you will have crunchy, crisp, fabulous lettuce.

Lettuce actually needs a good amount of airflow, in addition to a bit of moisture, in order to stay crisp. That’s why restaurants store their lettuce in special perforated bins that allow for air circulation while it’s held in the fridge.

Lettuce should be fresh and crisp but upon storage water will eventually evaporate. The pressure inside the cells drops and the leaves shrink and become less appetizing. The water will then diffuse back into the cells again. The process is known as osmosis [wikipedia].

Place your wilted greens in a bowl, cover them with cold water, and add ice cubes (optional). Wait 20 minutes to 1 hour for the magic to happen! Whenever we would eat dinner at my Grammie’s house, she would put the lettuce for the salad in a big bowl with water and ice cubes. Grammie said it made the lettuce crispy.

Once the lettuce is clean, put on the lid and turn the handle, spinning the lettuce until dry. In addition to cleaning lettuce, you may want to consider adding a couple tablespoons of salt to the water to help eliminate any possible bacteria that may be present.

1. A restaurant salad has salt on it. A great salad almost always has salt in it — and often more than you might expect. Most good restaurants season salad carefully — probably adding salt and pepper directly to the greens, not just the dressing.

Yes to salad spinners. Yes, salad spinners do take up a lot of cabinet space, but they provide more than enough value, and are worth every inch of space. And even if you didn’t quite have the room for it, you’d find a way to make room because that’s just how important this tool is in your kitchen.

1The Spinning Towel Method

Lay out a dish towel or tea towel, then place your wet lettuce (or in this case, spinach) in the center.
