WARNING: If a jar is not sealed or has a leak, use its contents
immediately or restart the canning process within 24 hours.
24.
Wipe the jars with a damp cloth and then dry them. Attach labels
displaying the date and contents. Keep the jars in a cold, dry place.
WARNING: The jars should not be exposed to freezing conditions, as
this may cause the liquid to expand and break the glass.
Troubleshooting
PROBLEM: liquid spills out of the jars. Causes and solutions:
1. The jars are overfilled.
When the contents and liquid are brought to a boil, they expand. If there
is no more space, the liquid spills out of the jar. Leave a space of 1/2 to 1
1/2-inches (1.25 to 2.5 cm).
2. There are air bubbles trapped in the jar.
When the contents are brought to a boil, the air bubbles force the liquid to
spill out of the jar.
Before closing the jar, release the trapped air by sliding a plastic spatula
along the inside of the jar.
3. The pressure level fluctuates during the canning process.
If the cooking temperature is not constant, sudden pressure changes can
occur, causing the liquid to spill out. Once the operating valve has begun to
release steam, make sure the heat source fluctuates, slowly going up and
down. Avoid pressure changes caused by the heat source.
4. The pressure drops rapidly after the canning process.
If the pressure is reduced too quickly, for example by placing the pressure
cooker under cold running water or frequently moving the operating valve,
the internal pressure may fall too quickly in both the pressure cooker and the
jars, making the liquid spill out.
Let the pressure cooker cool at room temperature. After 40 to 45 minutes,
check if the pressure has dropped by moving the operating valve.
PROBLEM: the jars break. Causes and solutions:
1. Supermarket jars having contained store-bought contents were
used instead of specialty canning jars
Only use jars specifically intended for home canning.
2. Damaged jars were used.
Used jars may have invisible cracks. The jars may also have been damaged
during transport. Each jar must be carefully inspected before being used.
