Pressure cookers and preserving kettles

Pressure cookers and preserving kettles are cooking appliances that are used to prepare food faster or preserve food for a long time.

They work by using pressure or high temperature: pressure cookers increase pressure to shorten cooking times, while canning kettles heat jars to preserve food airtight.

They are used in households and professional kitchens for preparing meals, preserving vegetables, fruit and other shelf-stable products.
