Equipment

  • water bath canner
  • blender
  • mesh sieve
  • cheesecloth
  • large pot
  • jars
  • lids
  • rings
  • jar lifter
  • Kitchen towel

Ingredients
  

  • 6 cups watermelon juice puréed and strained
  • 4 cups bottled lemon juice
  • 6 cups granulated sugar

For Serving

  • 1 part concentrate mix with water
  • 1.5 parts still or sparkling water

Instructions
 

  • Prepare a water bath canner and sterilize jars, lids, and rings. Ensure the canner is preheated to 180°F (82°C).
  • Purée watermelon chunks and strain through cheesecloth to obtain 6 cups of juice.
  • Combine watermelon juice, lemon juice, and sugar in a large pot. Heat to 190°F (88°C) without boiling, stirring frequently.
  • Ladle hot concentrate into prepared jars, leaving 1/4-inch headspace. Remove air bubbles, wipe rims, and secure lids fingertip tight.
  • Process jars in the water bath canner for 10 minutes, adjusting for altitude if necessary.
  • Remove jars and let them cool undisturbed on a towel-lined surface for 12 to 24 hours.
  • Check seals after cooling. Refrigerate any unsealed jars for immediate use.
  • Store sealed jars in a cool, dry, dark place for up to 6 months.
  • To serve, mix 1 part concentrate with 1.5 parts water.

Notes

  • Watermelon needs acidification for safe canning; bottled citrus juice is recommended for consistency and safety. Do not boil the mixture to prevent pectin setting.
  • Lime juice can be substituted for lemon juice. Always adjust processing times for your specific altitude.

Notes

Watermelon has a pH of 5.2 to 5.6 and requires acidification (lemon or lime juice) to reach a pH of 4.6 or lower for safe canning. Bottled citrus juice is recommended for consistency and food safety. Do not boil the mixture, as this may cause pectin in the lemon juice to set. Lime juice can be substituted for lemon juice. Altitude adjustments are required for processing time based on elevation.
