Equipment Needed
To can green beans using a Mirro pressure cooker, you will need the following equipment:
– Mirro pressure cooker
– Canning jars and lids
– Jar lifter
– Acid tester (optional)
– Green beans
– Salt (optional)
– Water
Preparing the Green Beans
Before canning, it is essential to prepare the green beans properly. This involves washing, trimming, and packing the beans into the canning jars.
Washing and Trimming the Green Beans
Start by washing the green beans in cold water to remove any dirt or debris. Then, trim the ends of the beans and remove any strings or blemishes. You can leave the beans whole or cut them into smaller pieces, depending on your preference.
Packing the Green Beans
To pack the green beans into the canning jars, start by adding a small amount of salt to the bottom of each jar, if desired. Then, pack the green beans into the jar, leaving about 1 inch of headspace. You can add water to the jar, making sure to leave the recommended headspace.
Canning the Green Beans
Once the green beans are packed into the jars, it is time to can them using the Mirro pressure cooker.
Preparing the Mirro Pressure Cooker
Before canning, make sure the Mirro pressure cooker is in good working condition. Check the gasket and valve for any signs of wear or damage, and replace them if necessary. Then, add the recommended amount of water to the pressure cooker, usually about 2-3 inches.
Processing the Green Beans
Place the jars into the Mirro pressure cooker, making sure they are covered by at least 1 inch of water. Close the lid and ensure the valve is set to the “sealing” position. Then, heat the pressure cooker over high heat until it reaches the recommended pressure, usually 10-15 PSI. Once the pressure is reached, reduce the heat to medium-low and process the green beans for the recommended time, usually 20-30 minutes.
Cooling and Storing the Canned Green Beans
After processing, turn off the heat and allow the pressure cooker to cool naturally. Once the pressure has returned to zero, remove the jars from the pressure cooker and let them cool to room temperature. Then, store the canned green beans in a cool, dark place, making sure they are not exposed to direct sunlight or moisture.
Safety Precautions
Canning green beans using a Mirro pressure cooker requires some safety precautions to ensure that the process is done correctly and safely.
Following Safe Canning Practices
It is essential to follow safe canning practices to avoid spoilage and foodborne illness. This includes:
– Using a tested recipe and following the recommended processing times and pressures.
– Ensuring the Mirro pressure cooker is in good working condition and the gasket and valve are not damaged.
– Keeping the canning area clean and sanitized.
– Handling the hot jars and pressure cooker with care, using a jar lifter and oven mitts.
Avoiding Common Mistakes
Some common mistakes to avoid when canning green beans using a Mirro pressure cooker include:
– Insufficient processing time or pressure, which can lead to undercooked or spoiled green beans.
– Incorrect headspace, which can cause the jars to not seal properly.
– Not following safe canning practices, which can lead to foodborne illness.
