Pressure canning is an essential skill for anyone looking to preserve their own food, whether you're growing your own vegetables, raising animals, or simply want to take advantage of seasonal produce. Pressure canning allows you to safely preserve low-acid foods such as meats, poultry, and vegetables that might otherwise spoil. While the process might seem intimidating at first, having the right pressure canner can make all the difference, especially for beginners.
In this guide, we'll walk you through everything you need to know about selecting the best pressure canner, step-by-step instructions for use, and tips for beginners to get the most out of their pressure canning experience.
Pressure canning is the only safe method for canning low-acid foods. Unlike high-acid foods such as fruits and pickles, which can be safely preserved through water bath canning, low-acid foods require the high temperatures achieved in a pressure canner to destroy harmful bacteria such as Clostridium botulinum, which causes botulism.
Here's why pressure canning is an essential tool:
For beginners, choosing the right pressure canner is crucial to ensure that you get reliable results every time. Here are the most important features to consider when selecting your canner:
Pressure canners come in various sizes, typically ranging from 10 to 23 quarts. For beginners, a 16 to 22-quart canner is usually ideal. A smaller canner may not fit as many jars, while a larger one may be too heavy to handle.
Pressure canners are generally made from aluminum or stainless steel.
A pressure gauge is critical to ensure you're applying the right amount of pressure for proper canning. There are two main types:
Safety is paramount when pressure canning. Look for canners with the following features:
For beginners, look for a canner that is easy to use and understand. It should come with clear instructions and a user-friendly design, including easy-to-read gauges, secure locking mechanisms, and handles that make it easier to lift and move.
Now that you have the basics of choosing a pressure canner, let's walk through the step-by-step process of using it for the first time. Follow these instructions for success:
Before you begin, make sure that the food you plan to can is properly prepared. Vegetables should be cleaned and cut, meats should be cooked or processed as needed, and jars should be sterilized. Refer to a trusted canning recipe for the food you're preserving to ensure you're following safe practices.
Carefully place your filled and sealed jars into the canner. You should use a jar rack to prevent the jars from touching the bottom directly, as this can cause them to crack under pressure.
Close the canner lid and lock it into place. Turn the heat on to medium-high. As the canner heats up, steam will begin to escape through the vent. Let the canner vent for 10 minutes to ensure that all the air is purged from inside, which helps the pressure to build evenly.
After venting, set the pressure to the level indicated by your recipe (usually 10-15 pounds of pressure, depending on altitude). If using a dial gauge, this is when the needle will start to move. If using a weighted gauge, you'll hear the weight start to jiggle.
Once the canner reaches the desired pressure, reduce the heat to maintain a steady pressure. Set a timer for the required canning time, which will vary based on the type of food and its density.
Once the canning time has passed, turn off the heat. Allow the canner to cool down naturally. Do not attempt to open the canner until the pressure has fully dropped, as this can lead to the jars breaking.
Once the canner has fully depressurized, carefully remove the jars. Let them cool completely, and check each one to make sure the seal is intact. You should hear a "pop" sound as the jars seal, indicating they've been properly sealed.
Once the jars are cooled and sealed, store them in a cool, dry place. They're now ready to be enjoyed!
