How to store lettuce?

To keep lettuce crispy, we need moisture and airflow. 

In the fridge:

  • To store a full head of lettuce, first of all, wrap lettuce in a paper towel and then put the head inside a plastic bag. And store it in the fridge. 
  • If you want to store individual lettuce leaves, after washing spin them dry. Then place in a lettuce keeper in the fridge. 
  • For airflow, keep a corner open if you are using a plastic bag.
  • Stemless lettuce can be stored by wrapping it in a wet paper towel in your crisper drawer.
  • To absorb the excess amount of moisture add a few paper towels. If paper towels get too damp then replace them after a few days.
  • Even if all conditions are favorable, lettuce may wilt a little bit.
  • For slightly wilted lettuce, crisp it and then soak the cut lettuce in ice water for a few minutes. And then spin and dry them.
  • Always keep them away from ethylene fruits such as pears, avocados, apples, and tomatoes. When these fruits ripen they release gas. The gas causes other products to age prematurely. 

In the freezer:

  • If you want to store lettuce for a much longer time then freeze them properly.
  • Thicker lettuce like romaine and butterhead can be frozen. Freezing lettuce can remove its flavor and crispiness. 
  • You can freeze lettuce for making smoothies, soups, and stews.

There are two ways of freezing lettuce

1st method:

Freezing full lettuce leaves:

For this method, separate and rinse off leaves of lettuce. Remove excess water with the help of a paper towel. After this, place them in a sealed container or a freezer bag.
