6. Wipe and Seal
Clean the jar rims with a cloth to remove any residue, then secure tightly with the lids.

7. Prepare for Pasteurization
Line the bottom of a deep pot with a cloth or towel to cushion the jars. Place them upright, then fill the pot with water until it reaches just below the lids.

8. Pasteurize the Jars
Bring the water to a gentle boil, then reduce heat slightly. Pasteurize for 30 minutes—enough to kill bacteria while preserving texture.

9. Cool the Jars Slowly
After 30 minutes, turn off the heat and let the jars cool in the water. This slow cooling strengthens the seal and prevents cracks.

10. Store Properly
Once fully cooled, dry the jars and store them in a dark, cool place. Properly sealed jars will last for months.

Tips for Success

• Refrigerate after opening and finish within a week.
