Pressure cooking is a skill. However you can learn this skill fairly easily if you have the time and the care to learn. You should definitely follow instructions on how to use a pressure cooker to the letter. There have been several accidents when using a pressure cooker but it is usually because the person using it was not doing it correctly or they had faulty equipment. You should have a pressure gauge tested every year to make sure it is in proper working order. You can do so at your local extension office. If you buy a cooker at a flea market or yard sale take you should definitely have it tested before using.
Presto makes three different types of six quart pressure cookers, the 6 quart aluminum, the 6 quart stainless steel, and the 6 quart stainless steel electric. They are all very nice, the first two the only difference is the type of metal it is made of. The two non-electric pressure cookers are made for use on glass/ceramic and flat top and regular stoves, the aluminum model number is 01264. The stainless steel is 01362. The electric pressure cookers model number is 02160. The 6 quart pressure cookers are made only to cook in, NOT to be used as a canner to preserve foods. All three of these models have a twelve year limited manufacturer’s warranty on them. All of these cookers do have replacement parts available if something happens to the original; just make sure you know the correct model number of your particular pressure cooker. The aluminum and the stainless steel come with a recipe/instruction booklet, and a canning rack and the electric pressure cooker comes with the 64 page recipe and instruction booklet. They all three hold six quarts of liquid (that's the reason it is called a six quart pressure cooker). Each of the pressure cookers come with a regulator weight set at 15 psi. The regulator maintains the proper cooking pressure automatically. These are supposed to cook food 3 to 10 times faster than other food preparation methods. Pressurecooker-outlet.com carries all three models of the 6 quart pressure cookers, the aluminum is $29.99, the stainless steel is $51.95, and the electric is $69.99 on this site.
