I need a new canner. My old one belonged to my mom. I have had it 20 yrs and the gasket and pressure jigger< > have been lost over the years of my not using it. I could get replacements, but the serial number on the bottom is so scratched and worn from being used as a soup/chili pot that I cannot make them out anymore. I had hoped to be able to afford one of the metal on metal ones this year, but I will not be able to. Wally world has 2 different sizes of Presto canner on the website, 16 qt and 23 qt. According to the info, both will hold 7 quart jars. It says the 16 qt will hold 10 pints. The 23 will hold 20 pints according to a question answered on the website. I don't understand how you can get 20 pints but still only 7 qts unless it comes with a rack so you can double stack the pints. Does anyone know? My tomatoes are beginning to bloom, and my semi runner green beans are sending out runners, so it will not be long until I will be needing the canner, I hope!!!
