Therefore, it is imperative that you always boil canning jars for the recommended time before sealing them.
do you have to preheat jars before canning?
Jars don’t need to be preheated before canning. Sterilization is the key to canning, and that is achieved through the processing time in the canner, not by preheating the jars. In fact, preheating jars can cause thermal shock, which can lead to breakage. Always start with clean jars. Wash them in hot soapy water and rinse them thoroughly. You can sterilize the jars by boiling them in water for 10 minutes. Or, you can sterilize them in the dishwasher on the sanitize cycle. Once the jars are sterilized, they are ready to be filled with food and processed in the canner.
why do you sterilize jars before canning?
The intention behind sterilizing jars before canning is multifaceted. It ensures the jars are free of contaminants and microorganisms, such as molds, bacteria, and yeasts, that can cause food spoilage or pose a threat to your health. Sterilization creates a clean environment for preserving your canned goods, preventing spoilage and extending the shelf life. Additionally, it eliminates any lingering flavors or odors that could affect the taste of the canned food. Sterilization of jars is crucial in food preservation, as it plays a vital role in ensuring the safety and quality of your canned goods.
