Testing Jar Seals

1. Press the middle of the lid with finger. If lid springs up when you release your finger, it is sealed.

2. Tap the lid with the bottom of a teaspoon. If sealed, you will hear a high-pitched sound.

3. Hold jar at eye level and look across the lid. The lid should be concave if sealed.

If lids fail to seal, it can be reprocessed with a new lid within 24 hours.

For sealed jars, remove bands.

Label and date jars.

Enjoy a pantry filled with your garden's harvest year-round.
