Introduction to Pressure Cookers

A pressure cooker is a kitchen appliance designed to cook food quickly and efficiently by using high pressure and temperature. It works by trapping steam inside the cooker, which builds up pressure and allows the food to cook faster than it would with traditional cooking methods. Pressure cookers are ideal for cooking a variety of foods, including meats, vegetables, and grains. They are also great for tenderizing tough cuts of meat and cooking beans and legumes.

How Pressure Cookers Work

Pressure cookers work by using a tight-fitting lid to trap steam inside the cooker. As the food cooks, the steam builds up pressure, which increases the boiling point of the water. This allows the food to cook faster and at a higher temperature than it would with traditional cooking methods. The pressure cooker also has a safety valve that releases excess pressure, preventing the cooker from exploding.

Introduction to Canners

A canner is a device used to preserve food by packing it into airtight containers and heating it to a high temperature to kill off bacteria and other microorganisms. Canners are designed specifically for canning and are typically larger and more heavy-duty than pressure cookers. They are ideal for preserving fruits, vegetables, meats, and soups.

How Canners Work

Canners work by using steam to heat the food to a high temperature, typically 212°F (100°C) or higher. The food is packed into airtight containers, such as jars or cans, and then placed in the canner. The canner is then sealed and heated, allowing the steam to build up pressure and kill off any bacteria or other microorganisms that may be present. The canner also has a safety valve that releases excess pressure, preventing the canner from exploding.

Types of Canners

There are two main types of canners: water bath canners and pressure canners.
