Why glass jars are dried well in the sun before filling pickles?

Glass jars are dried well in the sun before filling with pickles to ensure that any moisture inside the jars is eliminated. Excess moisture can promote the growth of bacteria and mold, compromising the preservation process. Additionally, drying the jars helps to create a vacuum seal when the pickles are added, enhancing the longevity and safety of the preserved food. This practice is essential for maintaining the quality and shelf-life of the pickles.
