Sous Vide Canning – Everything You Need to Know

The practicality of the sous vide canning method makes it a unique pasteurization and canning technique.

Sous vide is one culinary trend that has gotten good press over the past few years.

Sous vide is a French phrase that means ‘under vacuum’ and is pronounced ‘sue veed.’

The general idea of this cooking and canning process is to result in evenly cooked food with a lengthier shelf life.

If you’re a culinary expert or enthusiast, you may be more familiar with the sous vide cooking method using a vacuum-sealed bag or a ziplock, but we can’t say the same for sous vide canning, a new culinary concept.

Here’s everything you need to know about this new canning concept.

What are sous vide canning?

Sous vide canning is a unique low-temperature canning procedure that effectively promotes the shelf life of canned foods.

In sous vide canning, you place the food in an airtight canning jar and seal it before submerging it in a pre-heated water bath to cook halfway.

Sous vide canning uses an immersion circulator to evenly distribute heat across the water that the canned food is submerged in. The immersion circulator maintains a stable temperature during the sous vide canning process.

An interesting fact about sous vide canning is that it is a better canning method for acidic eats compared to conventional canning techniques.

  • Make sure the rim of the jars is free from salsa or random particles to give the jars a decent seal.
  • When you pour the salsa into the jar, leave some space at the top to allow for expansion when heating.
  • Use an air freer spatula to eliminate air bubbles when you pour the salsa into the jars.

Some grains expand as they cook and will, of course, need space to do that, so using the same jars you would use for foods like beans that expand only a little will not be self-serving.

  • Monitor the waterline when you submerge the jars in hot water to prevent water from entering the jars.
  • Put the canning jars into the water bath as the immersion circulator warms the water to prevent the jars from breaking due to thermal shock.
