Ingredients Method Notes

Ingredients
  

  • 6 –8 medium fresh grapefruits preferably ruby red
  • Water for syrup and processing
  • 2 –3 cups sugar adjust to taste
  • Optional: 1/4 cup honey 1 tsp vanilla extract, 1 cinnamon stick per quart
  • Pro Tip: For sugar-free canning use grapefruit juice or low-sugar pectin. Ruby red varieties work best for natural sweetness.

Method
 

  1. Wash grapefruit thoroughly. Peel and remove all white pith to prevent bitterness. Segment fruit and remove seeds.
  2. In a saucepan, combine water and sugar (4:1 ratio) for light syrup. Bring to a gentle boil until dissolved. For sugar-free options, use juice or honey water.
  3. Pack grapefruit segments into sterilized hot jars, leaving 1/2-inch headspace. Pour hot syrup over fruit, maintaining headspace.
  4. Remove air bubbles, wipe rims clean, and apply warmed lids. Process in a boiling water bath canner for 10 minutes, adjusting for altitude as needed.
  5. Cool jars for 12–24 hours. Check seals before storing in a cool, dark place.

Notes

Remove all pith to avoid bitterness. Never boil lids—keep them warm. Maintain 1/2-inch headspace for proper sealing. Ruby Red and Rio Red varieties are best for canning grapefruit.
