Canned Berries
Ingredients
Directions

If there is excess juice, dip it out with a cup before adding sugar.
Fill cans with the hot mixture, ensuring they are overflowing before sealing.

The step that matters
Fill the cans with hot mixture until overflowing, then seal. Filling hot and overflowing pushes air out of the jar. As the contents cool, they contract and a partial vacuum can form that helps the lid seal.
