Do you have a curiosity about canning? There might have been a time where you realized the lids didn’t create a popping noise after the processing phase.

Let me offer my practical insights into what to do if your canning lids don’t pop and provide simple steps to ensure your canned goods are safe and ready to enjoy.

7 Steps To Take If Canning Lids Don’t Pop

1. Wait Patiently

If your canning [1] lids don’t pop immediately after processing, don’t fret. Give the jars some time to cool down naturally. The popping sound might not happen right away. 

“Cooking is not difficult. Everyone has taste, even if they don’t realize it. Even if you’re not a great chef, nothing stops you from understanding the difference between what tastes good and what doesn’t.”

– Gerard Depardieu, Actor

Let the jars sit undisturbed for up to 24 hours. This waiting period allows the vacuum inside the jar to create a seal as the contents cool naturally. 

Remember, patience can be the key to a successful canning outcome.

2. Check for Indentation

If you’re concerned about your canning lids not popping, a simple yet effective step is to press down on the center of the lid gently. 

A properly sealed lid will have a concave indentation. If you notice this slight dip in the center of the lid, it’s a positive sign that the vacuum seal has been achieved. 

This small but significant detail can provide reassurance that your canning process is on the right track.

3. Listen for the “Thunk”

In the world of canning, the absence of a traditional pop sometimes means failure. While waiting for your lids to seal, listen closely for a subtle but reassuring sound—a quiet “thunk.” 

Sometimes, the jars emit this gentle noise as they cool and create a vacuum seal.

So, if you don’t hear the expected pop, keep your ears tuned for this understated confirmation that your canning endeavor is headed in the right direction.

4. Test the Seal


If the familiar pop is missing from your canning process, it’s time to take matters into your own hands. Once the jars have cooled down, remove the screw bands and gently lift each jar by its lid’s edge. 

You’ve achieved a successful seal if the lid holds firm and doesn’t come off. However, if the lid easily comes off, it’s an indication that the seal might not have formed correctly. 

This hands-on test provides valuable insight into the sealing status of your canned goods.

5. Refrigerate or Reprocess

Discovering that your canning lids have yet to pop doesn’t spell disaster. 

Firstly, refrigerate [2] any jars with unsealed lids and plan to consume their contents within a reasonable time frame.

Alternatively, you can choose to reprocess these jars using fresh lids. This involves reheating the contents, replacing the lid, and processing again. 

While reprocessing can be a bit of extra work, it’s a reliable way to ensure the safety and longevity of your canned goods.

6. Inspect for Flaws

If your canning lids have yet to pop, it’s wise to closely examine both the jar rim and the sealing compound on the lid. Check for any nicks, cracks, or irregularities that might prevent a proper seal. 

Even the tiniest flaw can disrupt the sealing process. Ensure the jar rims are smooth and free from imperfections and that the sealing compound on the lids is intact and even. 

Addressing any issues in this department can significantly enhance your chances of achieving successful seals in your canning endeavors.

7. Learn and Adapt
