🍴Instructions

Step One: Prepare supplies

Step three: Add Sugar and boil

Step Six: Process

Carefully lower the jars into a boiling water canner. Allow the water to return to a full rolling boil, then process for ten minutes.

Remove the jars and let them cool on a clean towel on the counter. You will hear a pinging sound as they seal. The lids should be firm and not flex when pressed in any way.

🥫 Storage instructions

Like all canned foods, the jam should be stored in a dark, cool place. A basement is perfect.

Your jam will be safe to eat for 12-18 months after canning.

If you have any jars that don’t seal, put them in the fridge and eat within a few weeks.
