It’s not about better—it’s about what you’re canning. Pressure canning vs Water bath.

  • Use water bath for high-acid foods like jams and pickles.
  • Use pressure canning for low-acid foods like vegetables, meat, and soups.

Each has its place.

Let me reassure you: Once you understand what each method does (and when to use it), you’ll be well on your way to knowing what canning recipe to use and confidently filling your jars.


The Boiling Basics: What Is Water Bath Canning?

Water bath canning is the easier of the two methods—and a great place to start. The basic steps are: fill your jars, leave correct headspace, add lids, and place jars in a pot of boiling water, process for a set time, and call it done. No pressure gauge. No scary valves.

Best for high-acid foods like:

Because these foods are naturally acidic, the boiling water is enough to destroy bacteria and spoilage organisms. Vinegar is what makes some vegetables safe in a water bath. Pickled carrots anyone?

Bring the Heat: What Is Pressure Canning?

Now let’s talk about pressure canning. This method is for the serious stuff—low acid vegetables and meat that need higher temperatures (240–250°F) to kill off harmful bacteria like Clostridium botulinum (you know, the botulism one).

Wait, There’s Steam Canning Too?

Yes! Steam canning is a third option approved for high-acid foods. I figured I’d mention it here. It works as an alternative to water bath canning but uses steam instead of boiling water. It’s faster, uses less water, and heats up quicker.

Which Method Do You Need? Pressure or Water bath?

If you’re only planning to can fruit, jam, or pickles, water bath might be all you need. But if you’ve got a garden full of green beans or want to preserve your famous beef stew, pressure canning is a must.
