Instructions:
Step 1: Clean the Watermelon
Start by washing the outside of the watermelon thoroughly using a bit of bicarbonate of soda (baking soda) and water. This ensures any dirt or contaminants on the rind are removed before slicing.
Step 2: Slice and Cube the Watermelon
Cut the watermelon in half, then into large slices. From these slices, remove the rind and cut the red, juicy flesh into medium-sized chunks. Make sure the pieces can fit easily into your jars.
Step 3: Pack into Jars
Place the watermelon pieces tightly into clean and dry glass jars. Fill each jar to the top, leaving a little space for the dressing.
Step 4: Preheat with Boiled Water
Pour boiling water into each jar until filled. Cover each jar loosely with a lid and let it sit for 20 minutes. This step softens the fruit and prepares it for preservation.
Step 5: Prepare the Dressing
After 20 minutes, carefully pour the water from the jars into a large pan. For each jar, add:
- 6 tablespoons of sugar
- 2 tablespoons of salt
- 2 teaspoons of citric acid
Stir and bring the mixture to a boil. This will become the preservation liquid.
Step 6: Final Fill and Seal
Once the dressing has boiled, pour it back into the jars, filling them completely. Immediately seal the jars with new, sterilized lids.
Step 7: Cool and Store
Allow the jars to cool gradually at room temperature. Once cooled, store them in a dark, cool place — such as a pantry or cellar. Properly sealed, the jars can last for several months, and you’ll be able to enjoy watermelon all year round.
