All American 921 21-1/2-Quart Pressure Cooker/Canner

This heavy-duty pressure cooker's large capacity is probably best utilized for canning (though it would also be great for a number of cooking tasks). A pressure cooker is generally recommended when canning vegetables and nonacid fruit, since the high heat that can be generated will kill more bacteria than a regular hot water bath. Made from cast aluminum, with sturdy screws to seal the lid to the pot, this pressure cooker requires no rubber or plastic gaskets or rings. Its 21-1/2-quart capacity holds 19 pint jars or 7 quart jars. A three-setting pressure regulator valve is included, and the pressure gauge gives a clear reading. Made in Wisconsin, this is an American classic.

This is a great product. I've used it several times to put up beans from the garden. This model allows me to put in seven quarts at one time. If I wanted, I could stack fourteen pints into the canner. The metal to metal seal works great and it is easy to get the lid on evenly. The weighted pressure valve is a very safe way to regulate the pressure. I would highly recommend this type of pressure cookers to anyone.

If you want to pressure can food at home this is the business. Well made and easy to use it offers you the opurtunity to effectively and safely can food. If you just use it as a large saucepan you can also use it for hot water bath canning as well. All in all a great bit of kit that should last for years (great that it uses a metal to metal seal on the lid/body so no gaskets to perish). 

Note that a litre kilner jar is not the same dimensions as an American quart jar so you can only fit 6 in at a time not 7 as per quart jars.
