Raspberry Pear Jam
When the jars have cooled, press the center of each lid to check the seal. If the dip in the lid holds, the jar is sealed. If the lid bounces up and down, the jar isn't sealed. If you have a jar that has not sealed, you can store the jam in the refrigerator for up to 3 weeks. Label the sealed jars with the content and date. Store in a cool, dry place for 1 year.
