It’s estimated that 88 millions tonnes of food waste are generated annually in Europe, the equivalent of €143 billion. As individual actors in the global food chain, we all have a part to play lowering waste, so let’s start with an easy step by discovering how to store vegetables in mason jars.

Storage in Glass Mason Jars

We like to store our vegetables in our Pearl glass mason jars. There are many reasons for this! For one, glass is a natural material that is easily recycled, whereas there are many environmental concerns surrounding the production and disposal of plastics. Plastic containers also tend to warp and change shape with food and temperature, whereas glass stores and performs safely across various temperatures.

The non-porous surface of glass also makes it easy to clean as it doesn’t absorb stains, food or germs. They can be safely washed in the dishwasher without warping or scratching the surface. Washing glass mason jars in the dishwasher, at high temperatures, also makes it easy to sanitize them. The non-porous nature of glass also means it doesn’t absorb smells the way plastic storage does, making glass a perfect option for storing foods with intense smells or colours.

We like to freeze the ends of our celery, carrots and onions to store in the freezer for making vegetable stocks for delicious soups.

Step 3: Drying

Make sure that everything is well dried to make sure there is no moisture that could lead to decay and rot. You can lay your vegetables out to dry naturally or you may pat them dry with a paper towel. You can also even place your vegetables on a wire rack with a towel underneath.

Step 4: Place in the Glass Mason Jar

Now you can begin to place your vegetables into your glass mason jars. To keep carrots, radishes and celery crunchy, you can feel up the glass mason jar with some water and keep them immersed, making sure to change the water every 3 days. 

For mushrooms, rather than screwing the glass lid on, we like to secure the top with a square of paper towel to provide more ventilation. To keep lettuce crisp, we like to add a paper towel that has been lightly spritzed with water at the end of the glass mason jar.
