To ensure the safety of your canned green beans, it’s critical to sterilize your jars and lids before use.
- Dishwasher Method: Place jars in a dishwasher on a hot setting. Leave them in the dishwasher until you’re ready to fill them.
- Boiling Method: Alternatively, you can boil the jars in water for about 10 minutes.
Make sure to also sanitize your canning lids according to the manufacturer’s instructions.
Step 3: Pack the Jars
Proper packing is key to successful canning.
- Filling the Jars: Using a canning funnel, pack the green beans into the jars, leaving about 1-inch headspace at the top.
- Salt Option: If desired, you can add about 1 teaspoon of salt to each quart-sized jar to enhance flavor. However, this step is purely optional.
Step 4: Add Water
Once the jars are filled with green beans, add water to each jar, ensuring you maintain the 1-inch headspace. Use hot water that has either been boiled or is on the stovetop.
Step 5: Remove Air Bubbles
Use a bubble remover or a clean, non-metal implement to gently slide down the sides of the jar. This action helps to release any trapped air bubbles. Afterward, check the headspace again, adjusting the liquid as necessary.
Step 6: Wipe Jar Rims and Apply Lids
To ensure a proper seal, it’s crucial to wipe the rims of the jars using a clean cloth. Remove any food particles or liquid that may have spilled onto the edges. Once clean, apply the lids and screw on the metal bands, but do not overtighten them.
Step 7: Prepare the Pressure Canner
- Add Water: Fill the pressure canner with the specified amount of water according to the manufacturer’s instructions (usually about 2-3 inches).
- Heat It Up: Place the canner on the stove over medium-high heat and close the lid.
Step 8: Process the Jars in the Pressure Canner
Once the water in the pressure canner heats up, steam will start to escape from the vent. Here’s what to do next:
- Allow steam to escape for about 10 minutes to ensure all air is removed from the canner.
- Seal the vent according to the pressure canner’s instructions. Begin to heat the canner until it reaches the recommended pressure (commonly 10-15 pounds of pressure depending on the altitude).
- Processing Time: The processing time for green beans usually varies based on whether you’re using pint or quart jars:
- Pints: Process for 20 minutes
- Quarts: Process for 25 minutes
Make sure to maintain a consistent pressure throughout the processing time. Adjust the heat as needed.
Step 9: Remove the Jars
Once the processing time is complete, turn off the heat and allow the canner to cool completely. Wait until pressure has returned to zero and gently open the canner lid—be cautious of hot steam!
Using the jar lifter, carefully remove each jar and place them on a clean kitchen towel or a cooling rack.
Step 10: Allow Jars to Cool and Check Seals
Let the jars cool undisturbed for 12-24 hours. Once completely cooled, check that the jar seals are secure. You can test the seal by pressing down in the center of the lid—if it pops back up, the seal is not good.
