Pressure canners and pressure cookers all look alike then. What is the difference between the two? These questions must have come to your mind. Can pressure cookers be used for canning, or can pressure canners be used for cooking? Before answering these questions, let’s first elaborate on the difference between pressure cooker and pressure canner.
Pressure Cooker Vs Pressure Canner
- It is usually made up of aluminum or stainless steel and includes a locking lid with rubber and pressure releasing vent.
- Some pressure cookers include a knob that allows different pressure settings; otherwise, it only has one pressure setting that depends on the heat of the stove.
- The lid of the vessel is closed, and the pressure is buildup inside the cooker when subjected to heat.
- The pressure buildup inside the vessel increases the boiling point of water, which results in cooking the food much faster than ordinary pots. For example, the beans that take 1 hour to cook can be prepared in less than 20 minutes under pressure.
- Pressure canners are larger in size as compared to pressure cookers as it must contain the jars that hold the food for canning. It also includes a locking lid and a vent just like pressure cookers.
- A pressure gauge is a must have for any pressure canner because without setting and monitoring the exact pressure, it becomes difficult to can food. unfortunately, it might not kill the bacterial inside the food.
- It is more sophisticated than pressure cookers as it measures the pressure inside the vessel.
- It works by sealing the top and building pressure inside the vessel.
- The food should be able to heat up at almost 240 degrees in order for it to kill the harmful bacteria and their spores. The higher temperature builds up high pressure inside the canner to achieve the desired results.
Can you use a Pressure Cookers as Canners? Difference between pressure cooker and pressure canner
The answer is simple.
No, they cannot be used as canners.
Pressure canners are more sophisticated than a pressure cooker, that’s why they are much expensive.
Pressure cookers don’t have any mechanism to measure the pressure inside the vessel. It is only suitable for cooking purposes. But if you want to do canning only once in a while, you can do so in a pressure cooker that generates 12-15 PSI pressure. Here is a list of some of the best pressure cookers for canning.
Canning in pressure is not advised by The National Center for Home Food Preservation. The pressure cookers are not suitable for canning large amounts of food as there is a risk involved of not killing the harmful bacteria.
Can you use a Pressure Canners for Cooking?
The answer is: Yes, most of the time.
The experts recommend not to cook the food that makes foam or bubbles under high pressure because the pressure vents might clog, and could lead to dangerous consequences. The two main brands of pressure canners in the United States are All American and Presto. They clearly state in their guides to avoid food such as rice, applesauce, cranberries, rhubarb, spaghetti, or any other food you think might foam.
The only way to cook the foaming food in a canner is to fill half the vessel with water. This way, the foam doesn’t reach the lid.
Can you use water bath for canning in a pressure cooker?
The answer is: Yes.
You can water bath the cans in a pressure cooker as long as you are not sealing the lid.
Can you use instant pot for canning?
The instant pot is actually the electric pressure cooker, which maintains the pressure digitally and has a heat source of its own. It doesn’t require heat from the stove to form pressure. People often rule against using a pressure cooker for canning purposes as you cannot regulate and monitor the pressure. The instant pot nowadays comes with specific features for canning. It allows the pressure to rise as high as 15 PSI, which is safe for canning food, according to The National Center for Home Food Preservation.
