TIme to remove the Jars form the Canner

  • When you remove hot jars from a canner do not retighten their jar lids. Retightening of hot lids may cut through the gasket and cause seal failures.
  • Cool the jars at room temperature for 12 to 24 hours.
  • Jars may be cooled on racks or towels to minimize heat damage to counters.
  • The food level and liquid volume of raw-packed jars will be noticeably lower after cooling.
  • Air is exhausted during processing and food shrinks.
  • If a jar loses excessive liquid during processing, do not open it to add more liquid.
  • Check for sealed lids before putting in storage.
