The Presto 23-quart pressure canner can hold up to 19 regular-sized canning jars. If you are using wide-mouth jars, the maximum capacity is 17 jars. You may want to double check the size of the jars and the capacity of the canner before you start canning to make sure that everything fits properly.
Additionally, you need to make sure that there is at least 1 inch of space between the top of the jars and the lid of the canner, so that the pressure can build up properly.
Does my pressure canner have to be full of jars?
No, your pressure canner does not have to be full of jars. In fact, it is not recommended to overfill your pressure canner because it could lead to uneven heating and water evaporation. The best practice is to fill your pressure canner with the proper amount of water, place your jars and other items in the canner and then add enough additional water to cover the tops of the jars by two inches.
Be sure to leave at least one inch of space between the top of the canner and the lid to allow for proper pressure to build during processing.
Can you put too many jars in a pressure canner?
No, you should not put too many jars in a pressure canner. The correct number of jars for a pressure canner varies depending on the size of the jars and the style and size of the pressure canner – for example, a 21-quart pressure canner can accommodate up to seven one-quart jars, or nine one-pint jars.
You should also leave some room for the water to boil and generate the pressure needed for proper canning. If the canner is overcrowded, the jars could obstruct the air vents and prevent the canner from pressurizing, resulting in under-processed food.
Additionally, adding too many jars in one batch can reduce the boiling water temperature, resulting in inadequate heat and insufficient steam. Therefore, it is important to be aware of your pressure canner’s capacity in order to prevent overcrowding.
Can you run a pressure canner half full?
No, you should never run a pressure canner half full. Pressure canners work by circulating boiling water or steam throughout the contents of the pot, which requires a certain amount of liquid to create enough steam and pressure.
By filling the canner only half full, there is not enough liquid to build up the correct amount of pressure needed to process the food safely. Additionally, the temperature will be lower than what is recommended and could result in spoilage of the foods or spoilage of the jars due to breakage due to uneven temperatures.
To ensure safe and successful canning, always fill the pressure canner with the recommended amount of water before starting the canning process.
Can you leave too much headspace when canning?
Yes, you can leave too much headspace when canning. Headspace is the amount of space left between the top of the food item and the lid of the jar. If you leave too much headspace it can cause the lid to buckle during processing, this can cause air to get into the jar and could lead to a spoiled product.
If food is packed too loosely, it can also cause the vacuum seal to not form properly, which can increase risk of spoilage. To ensure food safety when canning, make sure you follow the recipe and fill to the correct headspace as indicated.

What is the difference between a pressure cooker and a canning pressure cooker?
A pressure cooker and a canning pressure cooker are similar in terms of their construction and cooking capabilities, but there are some distinct differences between the two. A traditional pressure cooker is a closed pot that uses steam pressure to quickly cook food, while a canning pressure cooker is a specifically designed pressure cooker that is used for canning fruits and vegetables.
The canning pressure cooker is typically larger and heavier than a traditional pressure cooker, and it has two pressure settings—one for “processing” and one for “bottling”—that account for the different cooking times and temperatures needed for proper canning.
Additionally, a canning pressure cooker has a device called a vent port, which is used to control the pressure within the pot. The vent port allows the steam pressure to escape safely, as well as for additional water or other liquid to be added during the canning process.
Finally, a canning pressure cooker has a rack that is placed in the bottom of the pot to allow proper circulation of heat and steam, as well as to keep the jars of food off the bottom of the pot.
Is pressure canning really necessary?
Pressure canning is usually necessary when dealing with low-acid foods such as vegetables, meats, seafood, and even some fruits. Using a boiling water canner for these types of foods can cause spoilage and foodborne illnesses, so it is important to make sure you are using the correct canning method.
Pressure canning kills the bacteria, spores and enzymes that cause food spoilage and makes sure the food is able to be safely consumed. Pressure canning is a very important part of the canning process and should not be forgotten.
Can you do canning with a Instapot?

Is it okay to leave jars in pressure canner overnight?
No, it is not okay to leave jars in a pressure canner overnight. Pressure canning is an important process in preserving food; therefore aligning with the USDA guidelines is essential in achieving safe results.
Both the jars and the pressure canner must not be opened until the utmost safety can be ensured by following the instructions to the letter. Pressure must be allowed to cool naturally, without disruption caused by opening the lid too soon, or letting the jars remain in the canner overnight.
If the cooled jars remain in the canner, the temperatures of the newly canned food will not be accurate, affecting the safety and integrity of the food. Taking shortcuts or incorrectly following the directions puts your food at risk for spoilage and contamination.
What foods should not be pressure canned?
It is not recommended to pressure can a variety of different types of food. Pressure canning should not be used for foods which are low in acidity, like vegetables, mushrooms and meats. These types of foods should be pressure canned at a higher temperature or use a different type of canning method.
Additionally, it’s not recommended to pressure can dairy products, some oils, and garlic, as these may not be safe to consume after canning. High-acid foods such as fruits, jams, jellies, and tomatoes and their products, combined with added vinegar or acidity, can be safely pressure canned at 240°F.
Why did my pressure canner turned black?
Your pressure canner has likely turned black because of the build-up of residue from the food you have been canning. This residue is formed by the combination of the acids, oils and particles in the foods you are cooking, which then adheres to the surface of the canner.
This can be caused by not fully submerging the food in liquid, leaving the jars in the hot canner for too long and not adjusting the recipe for altitudes over 1,000 feet. You can prevent this from happening by thoroughly cleaning the canner after each use with a degreaser or detergent, as well as scrubbing any stuck-on bits using a canning brush or sponge.
Additionally, you should never leave the jars in the canner after processing and reduce the recipe’s cooking time each time you can something. With regular cleaning and paying attention to the instructions in the recipe, you should be able to avoid your pressure canner turning black.
