- Make sure to close the jars tightly. The lids must be very tightly closed to ensure airtightness.
- Place the jars in a pot with the lids facing down. Fill the pot with room-temperature water until it reaches halfway up the jars. Bring the water to a boil and let it boil over medium heat for 15 minutes.
- After boiling, turn off the heat and leave the jars in hot water for 2 hours. This will ensure that the lids finish closing properly. After that time, remove the jars and dry them with a cloth.
- Perform a lid test to make sure they’re sealed tightly. If the lids are flat and there is no swelling, you can store the jars in a cool place out of the sun.
