What is open kettle canning?

Open kettle canning is a method of home food preservation that involves filling jars with hot, prepared food and sealing them with lids. This method does not involve a pressure canner or water bath canner.

The process of open kettle canning involves cooking the food to be canned and then immediately transferring it to a hot jar. The jar is then filled with the hot food, leaving some headspace at the top, and the lid is quickly placed on top. As the food cools, a vacuum is created which helps to seal the jar.

While open kettle canning is a simple and convenient method, it is not recommended for preserving low-acid foods such as vegetables, meats, or poultry. These types of foods require a higher level of heat and pressure for safe canning.

Open kettle canning is most commonly used for high-acid foods such as fruits, jams, jellies, and pickles. However, it is important to note that this method carries a higher risk of spoilage and bacteria growth compared to using a pressure canner or water bath canner.

Overall, it is recommended to follow safe canning practices and use proper equipment to ensure the safety and longevity of preserved foods.
