Step 3: Sealing the Jars
Place the lids on each jar, ensuring they are properly seated. Then, use the band to screw on the lids until they are fingertip-tight—avoid over-tightening, as it can prevent the lid from sealing properly.
Step 4: Canning Time and Pressure
Processing Time
The canning time depends on the size of your jars. Here’s a quick reference:
- Pints: 20 minutes
- Quarts: 25 minutes
Pressure Settings
You generally need to maintain a pressure of 10-11 pounds. Different altitudes may require pressure adjustments. It’s essential to consult a reliable chart or your pressure canner’s manual to determine the correct settings based on your altitude.
Step 5: Cooling and Storing
Once the timing is complete, turn off the heat and allow the pressure canner to cool down naturally. This can take up to 30 minutes.
Opening the Canner
When the pressure gauge returns to zero, carefully open the lid away from you to avoid steam burns. Using the jar lifter, gently remove each jar and place them on a clean towel or cooling rack.
Checking the Seal
Let the jars sit undisturbed for 12-24 hours. You will know the jars are sealed if the lid is depressed inwards and does not flex when pressed.
Best Practices for Storing Canned Green Beans
Store your sealed jars in a cool, dark place, like a pantry or cupboard. It’s crucial to rotate your stock, consuming older jars first to minimize waste.
Tips for Successful Canning
- Always follow tested recipes and methods from reliable sources, such as the USDA.
- Avoid canning beans that are overripe, as they may affect the quality of your preserved product.
- Before consuming, inspect each jar for signs of spoilage, like bulging lids or unusual odors.
