The high quality and large capacity of the 21-quart All American Pressure Canner 921 make it the best bet for avid canners. Most importantly, the seal is reliable and safe. However, this is not as good of a choice for preparing meals or for casual canners as it is very large, heavy and pricey.
An ideal choice for canning. Owners consider the All American 921 21-Quart Pressure Cooker/Canner one of the top options of its kind on the market. It can hold 19 pint jars or seven quart jars, and it's often described as a joy to use. We saw no complaints of the canner failing during use and ruining any food being preserved. Because it's so large, most owners use this pressure canner/cooker exclusively for canning. Some do say they use it to cook large meals, like an 11-pound turkey, and it leaves the meat tender and moist. We also saw plenty of reports of people who use it to make large batches of broth or stew and they say the results are superb. It also comes in 10.5 quart, 15.5 quart, 25 quart, 30 quart and 41.5 quart capacities.
Simple design. The All American Pressure Canner 921 is described by owners as extremely easy to use. Instead of a gasket and a more complicated locking mechanism, it uses simple metal clamps to secure the top. The All American 921 also has an easy-to-read pressure gauge that users say is more precise than gauges on cheaper models. However, this cooker is very heavy -- so heavy that most owners say they can't lift it when it's full. Because of its heft, the manufacturer does not recommend its line of pressure canners for anyone with a glass or other smoothtop range. Before buying any canner, but specifically this large model, measure your range to ensure the canner will clear any vents or cabinets over the stove.
Fewer bells and whistles, but still safe. The All American 921 may have fewer safety features than some other pressure cookers, but reviewers say this unit is very safe thanks to its metal-to-metal seal. It does have two backup safety precautions if the unit becomes over-pressurized: the safety-control valve and over-pressure plug. The lack of a rubber gasket also means there are no parts to wear out and have to replace. Owners unanimously say that the stainless steel 921 pressure cooker canner is sturdy, reliable, high quality and may easily outlive its first owner. It comes with a one-year warranty and is made in America.
Kelly Rockwell of MyShinyKitchen.com writes a detailed buying guide on cookers and canners and recommends a handful. She recommends the entire All American line but says in the review that the 921 is her favorite for its capacity and is the unit that she owns. She does admit that she only uses the pressure cooker for canning, as it's too large for everyday cooking.
