Canning supplies are essential tools and materials used for preserving food in jars. The main items include canning jars, lids, and bands, which create a seal to keep food safe from spoilage. Other important supplies are canning pots for boiling jars, jar lifters for safe handling, and funnel for easy filling. In addition to these basics, some people may also use pressure canners for low-acid foods like vegetables and meats. Canning recipes often guide the process, ensuring that food is preserved safely and effectively. Proper canning supplies help maintain the quality and flavor of home-canned goods.
