Water bath canning is a method used to preserve high-acid foods, such as fruits, pickles, and jams. This technique involves placing jars filled with food into a large pot of boiling water. The heat from the water kills bacteria, yeasts, and molds, ensuring the food remains safe to eat for an extended period. To successfully use water bath canning, it is essential to ensure that the jars are properly sealed. After processing, the jars should be left to cool, allowing the lids to create a vacuum seal. This process helps maintain the quality and safety of the preserved food.
