Ingredients Method Notes

Ingredients
  

  • 10 –12 large fresh grapefruits about 10 lbs
  • 4 –6 cups water filtered preferred
  • 1 –2 cups sugar optional, for syrup
Substitutions:
  • Use honey or agave nectar instead of sugar.
  • For no-sugar canning replace syrup with unsweetened grapefruit juice.
  • Swap in oranges for a mixed-citrus version.

Method
 

  1. Wash grapefruits under cool water. Peel and remove as much white pith as possible. Separate segments and remove seeds.
  2. (Optional) Soak segments in 1 gallon of water mixed with 1 teaspoon pectic enzyme for 3 hours or overnight to reduce bitterness. Rinse well.
  3. Prepare water bath canner and sterilize jars and lids in hot water.
  4. In a saucepan, combine water and sugar (if using). Heat over medium until dissolved to make syrup, or warm plain water/juice for a sugar-free version.
  5. Pack grapefruit segments into jars, leaving ½ inch headspace. Pour hot syrup, water, or juice over fruit, maintaining headspace. Remove air bubbles and wipe rims clean. Seal jars fingertight.
  6. Process jars in boiling water bath for 10 minutes (add 5 minutes per 1,000 ft altitude). Remove and let cool 12–24 hours. Check seals before storing.

Notes

Use ruby red or pink grapefruit for sweeter, milder flavor. Always adjust canning times for altitude and ensure proper sterilization for safe, long-lasting preservation.
