Pressure Cookers vs. Canners: What’s the Difference?
When it comes to preserving food, pressure cookers and canners are two common tools that people use. While they may seem similar, there are some important differences between the two.
Pressure Cookers
A pressure cooker is a versatile kitchen appliance that cooks food quickly by creating a high-pressure environment. It is typically used for cooking meals but can also be used for certain forms of food preservation.
Pressure cookers are sealed containers with a locking lid that traps steam inside. The steam builds up pressure, raising the boiling point of water and allowing food to cook faster. This increased pressure helps to tenderize tough cuts of meat and cook food thoroughly.
While pressure cookers can be used for certain types of canning, they are not suitable for all types of canning, especially low-acid foods. This is because pressure cookers may not reach the high temperatures necessary to kill all bacteria, which can lead to food spoilage and the growth of harmful microorganisms.
Canners
Canners, also known as canning kettles or boiling water bath canners, are specifically designed for canning and preserving food. They are large, deep pots that are used to process jars of food in boiling water.
Unlike pressure cookers, canners use a boiling water bath method to preserve food. This method involves submerging jars of food in boiling water and maintaining a specific temperature for a certain amount of time. The heat kills bacteria, molds, and yeasts, creating a vacuum seal that keeps the food safely preserved.
Canners are ideal for canning high-acid foods like fruits, tomatoes, and pickled vegetables. They are not suitable for canning low-acid foods like meat, poultry, seafood, and most vegetables, as these foods require the higher temperatures and higher pressure that only a pressure canner can provide.
| Pressure Cookers | Canners |
|---|---|
| Used for cooking meals | Specifically designed for canning and preserving food |
| Create high-pressure environment | Use boiling water bath method |
| Tenderize tough cuts of meat | Kill bacteria, molds, and yeasts |
