Lettuce leaves

In the case of the fresh lettuce leaves, it is recommended to wash them first and dry them with the help of a paper towel or you can even dry them in the salad spinner. Afterward, take a bowl, put all the lettuce leaves in it, now take a damp cloth or paper towel and place it on the lettuce leaves. Lastly, wrap the bowl with the help of cling film or plastic wrap.

What is the optimum temperature to store the lettuce in the fridge?

You should always store your lettuce at 40°F or below in the fridge. Bacterial growth takes place at a faster pace between the temperature of 40°F and 140°F, therefore it is always advised to store lettuce at a lower temperature to preserve its freshness and quality for a long time.

How long does salad last at room temperature?

Salad lasts for about 2 hours when left at room temperature. The bacterial growth takes place at a faster pace between 40°F and 140°F so if a salad is kept out for more than 2 hours, there is a great chance that bacteria and other microbes will find their way to it and will spoil it. Moreover, the lettuce can become soggy and can limp when it is kept at room temperature for more than an hour or two.

Can I freeze my lettuce?
