Mason jars are versatile containers used for storing various goods, such as jams, sauces, pickles, and more. Sealing mason jars properly is essential to keep your food items fresh and prevent spoilage. In this guide, we will discuss the steps on how to seal mason jars effectively.
Materials Needed
Before you start sealing mason jars, ensure you have the following materials on hand:
- Mason jars with lids and bands
- Boiling water canner
- Canning funnel
- Jar lifter
- Non-metallic spatula
- Clean cloths
Steps To Seal Mason Jars
Follow these steps to properly seal your mason jars:
- Clean and Sterilize Jars
Before filling your mason jars with food items, make sure to wash them thoroughly with hot, soapy water. Sterilize the jars by boiling them in water for 10 minutes or placing them in the dishwasher.
- Prepare the Lids
While the jars are being sterilized, prepare the lids by simmering them in hot water. Do not boil the lids, as it may damage the seal.
- Fill the Jars
Using a canning funnel, fill the jars with your desired food items, leaving enough headspace at the top for proper sealing. Use a non-metallic spatula to remove any air bubbles in the jar.
- Apply Lids and Bands
Place the lids on top of the filled jars and screw on the bands until they are fingertip tight. Avoid over-tightening the bands, as it can prevent a proper seal from forming.
- Process in a Boiling Water Canner
Place the filled and sealed jars in a boiling water canner, ensuring they are fully submerged in water. Process the jars according to the recipe or recommended processing time for the food item.
- Remove Jars and Cool
After processing, carefully remove the jars from the canner using a jar lifter and place them on a clean cloth to cool. Allow the jars to cool undisturbed for 12-24 hours.
- Check Seals
Once the jars have cooled, check the seals by pressing down on the center of the lid. If the lid does not flex or make a popping sound, the jars are properly sealed. If the lid flexes, refrigerate the jar and consume the contents within a few days.
Tips for Sealing Mason Jars
Here are some additional tips to help you seal mason jars effectively:
- Use fresh lids for each canning session to ensure a proper seal.
- Do not reuse lids or bands, as they may not provide a secure seal.
- Avoid tightening the bands too much, as it can lead to seal failure.
- Store sealed mason jars in a cool, dark place away from direct sunlight.
- Label each jar with the contents and date of canning for easy identification.
