This vegetable can be found in a variety of colors, textures, and flavors and is a good source of nutrients, including vitamins, minerals, and fiber. It is a versatile food that can be used in many ways and will keep for a long time when stored correctly.

The first step to preserving lettuce is to thoroughly wash the leaves. To do this, fill your sink with cool water and gently swish the leaves around in it. This will remove any grit or dirt that may be stuck to the leaves and help extend their shelf life. After washing, dry the leaves. This can be done with a salad spinner, by laying the leaves on a kitchen towel, or by patting them dry with paper towels.
Oxygen and excess moisture are the biggest factors in wilted or slimy lettuce, so it is important to get the leaves as dry as possible before storage. After the lettuce is dried, it can be placed in a container or plastic bag with paper towels to absorb any additional moisture. If you use a plastic bag, make sure that it is an airtight one to keep oxygen out.
This method will preserve your lettuce for up to a week, depending on the variety and its original condition. This technique is also ideal for storing mesclun mixes or delicate greens like arugula and watercress.
