Can You Safely Can Foods in Supermarket Jars?

When it comes to canning, using the right jars is crucial. While many people wonder if they can reuse commercial jars such as those found at the supermarket, the answer is clear-cut: it’s not possible, and it’s not recommended. If you’re looking to get into home canning, you’ll want to invest in Mason containers specifically designed for the process. Why is this the case? Here are some key reasons to consider:
  • Commercial jars aren’t designed to withstand the high temperatures that are required during the canning process. This can lead to breakage or other issues that could compromise the safety and longevity of your canned goods.
  • Canning jars are made of tempered glass, which is specifically crafted to withstand high heat. This means that they’re less likely to break or shatter when exposed to the conditions necessary for home canning.
  • When you use commercial jars for canning, you may also be exposing your food to potential contaminants. This is because these jars aren’t typically sterilized in the same way that true canning jars are.
  • Overall, if you’re serious about home canning and want to ensure that your canned goods are safe, delicious, and long-lasting, Mason jars are really the only way to go. When you invest in good-quality canning jars, you’ll be able to enjoy all the benefits of home-canned foods without any of the risks that come with using subpar equipment.
