How to Store Watermelon
Refrigeration
You can store watermelons in the refrigerator. But keep in mind that refrigeration reduces the nutritional benefits and affects the look after a while.
Additionally, make sure the watermelon is clean and free from bacteria and dirt. Then cut them up and store them in zip-lock bags. This method applies if you are working with watermelons and their rinds.
However, if you wish to refrigerate your watermelon slices without the rind, de-seed them before storing them in sealable bags or airtight containers. This way, you preserve the flavor and freshness.
Freezing
Freezing watermelons extends their shelf life. Use an ice tray or popsicle mold to make ice cubes of blended watermelons.
You can add seasoning or blend it with other fruits to make frozen treats if you feel adventurous.
Pickling
Yes, we know it sounds strange, but you can store your watermelons by Pickling.
It’s pretty straightforward; all you need to do is:
- Get some lemon juice, vinegar, sugar, and spice. Then boil them.
- Next, slice your watermelon and put them in mason jars [1].
- Pour the cooked mixture inside the jars and cover. Allow to cool and store in your kitchen pantry.
Candying and Jellying
You can store your watermelons by turning them into candied treats or jellies. This form lasts longer than storing fresh watermelons.
