The Mirro 22-quart pressure cooker can certainly be used for cooking extra-large batches of stews, soups and chili, but thanks to its extra-large capacity it really shines as a pressure canner. It can hold up to 16 pint jars, 14 wide mouth pint jars, 30 half pint jars, or 5 quart jars. Made of rust-proof, heavy-gauge aluminum, the cooker has a stay-cool, locking handle, and it features three knobs that hold the internal pressure at one of three options--5, 10, and 15 PSI. Mirro pressure cookers are designed with safety in mind, and its Triple Safe Design includes a safety release plug, sure-locking lid system, and side gasket pressure release. It comes with complete instructions and a recipe booklet.
