Notes

Can this onion relish be canned using proper canning technique? This recipe uses instant pectin. You may be able to can this onion relish recipe however, you would need to use classic Ball's RealFruit pectin or universal pectin so it won't break down during the hot water bath when processing the jars. Start with one 1.75 ounce box (4 tablespoons) and adjust the thickness after boiling the onion relish adding more if needed, before ladling into the jars to can.
  • Prepare boiling water canner. Heat jars and lids in simmering water until ready for use. Do not boil. Set bands aside.  
  • Cook onion relish per the recipe using Ball's classic RealFruit Pectin or similar in place of instant pectin. (OR Universal pectin)

  • Place jar in boiling water canner. Repeat process until all jars are filled. 
  • Process jars for 15 minutes. Turn off heat; remove lid of canner and let jars stand for 5 minutes. (Please note, canning at high altitude may need longer processing time.)
  • Carefully remove jars using tongs (they're hot!) and set aside to cool. Check the lids for seal after 24 hours. Gently tap, the lid should not flex up and down when the center is pressed.
