Your garden has given you more green beans that you could possibly eat at once. Can your beans and make your summer bounty last all year long.
You Will Need2 lbs. green beans
1 tsp. canning salt
Quart-sized canning jar with lid
Paper towels
Pressure canner
Labels
Step 1: Wash and trim beans    清洗、整理豆子
Wash the beans and cut off the ends. Leave them whole or snap them into 1-inch pieces.
Step 2: Add beans to a jar    把整好的豆子放入罐子
Add the beans to the sterilized quart-sized jar. Fill the jar until the beans are 1 inch from the top and then add the canning salt.
Omit the salt if you are watching your sodium intake.
Step 3: Add boiling water    在罐子里加开水
Pour boiling water into the jar, leaving 1 inch of head space. Wipe the rim of the jar with a damp paper towel, place the lid on the jar, and secure it with the screw band.
Step 4: Transfer jar to a pressure canner      把罐子放入高压锅中
Place the jar in a pressure canner that has been prepared according to the manufacturer’s instructions. Set the pressure at 11 PSI for a dial gauge and 10 PSI for a weighted gauge.
Adjust the pressure if you are at a high altitude. Add 5 extra pounds of pressure if you are at an elevation over 1,000 feet.
Step 5: Process for 25 minutes    加工过程25分钟
Process your beans in the pressure canner for 25 minutes. Then carefully remove the jar and allow it to cool.
Never use a water-bath canner to can beans. Green beans are a low-acid food and must be processed in a pressure canner to ensure that all bacteria are killed.
Step 6: Check the seal on the lid   检查封条
Check the seal on the jar lid. Test flat, metal jar lids by pressing down on the center of the lid — a properly sealed lid won’t move.
Step 7: Wash, dry, label, and store jars   洗干净,晒干,贴标签,储存罐子
Wash, dry, and label the jars, and store them in a cool, dry place. When properly stored, your canned beans will be good for up to five years.
Green beans fall into a category often known as common beans. Scientists believe that these beans were first domesticated in Peru before 6000 B.C.E.
