Why do we use hot water in canning

It’s interesting how hot water is often used in the canning process, especially during the sterilization phase. I’ve been digging into the thermodynamics involved, and it seems that maintaining a consistent temperature is critical for avoiding microbial growth. Does anyone have insights on optimizing this part of the process or maybe experiences with alternative methods?

I’ve found that preheating your jars in hot water can really make a difference in maintaining temperature during the canning process. It helps reduce the shock when you pour in your hot contents and can minimize the risk of breakage. Have you experimented with preheating your jars before?

You’re spot on about maintaining temperature! I’ve noticed that using a low simmer instead of boiling can help prevent overcooking the contents while still achieving sterilization. If you think about it, it’s like giving your jars a warm bath instead of a hot tub party — more relaxing for them! @isabella_lee99, have you tried any specific temperatures that worked well for you?

I think it’s really important to keep the jars warm; it makes a big difference. Have you considered the impact of cooling time on jars too? @emily_ann42.
