To ensure that watermelon stays fresh when stored in glass jars, follow these steps for effective sealing and preservation:
Cut the Watermelon: Begin by cutting the watermelon into manageable chunks or cubes, depending on your preference.
Prepare the Jars: Use clean, sterilized glass jars with airtight lids. This helps prevent contamination and keeps the watermelon fresh longer.
Boil Water: Pour boiling water into the jars to sterilize them. Let the water sit for about 15 minutes, then drain it. This step helps kill any bacteria that could spoil the fruit.
Add Preservatives: After draining the jars, add a tablespoon of sugar, a teaspoon of citric acid, and a pinch of salt to each jar. These ingredients act as natural preservatives, enhancing the flavor and texture of the watermelon.
Fill with Hot Water: Pour fresh hot water into the jars, ensuring that the sugar and citric acid dissolve completely. Leave some space at the top of the jar to allow for expansion.
Seal Tightly: Immediately seal the jars with their lids while the contents are still hot. Ensure the lids are tightened securely to create an airtight seal.
