I have my moms old pressure cooker . Think its an presto. . Old but still works.has a sealed lid. Hard get lid off after canning . If u wipe little oil on seal before canning comes off lot easier. I usually just use a simple but odd water bath method. . Don t use pressure canner much. Boil lids couple minutes. After filling jars with pickles or pickled squash. Pour mixture of whatever im making into jars almost to the top.Put hot lids an bands on quickly. They will pop when sealed. I freeze peas,green beans,okra an make mater juice if have any left from making salsa. Freeze extra peppers for making chili in winter time.
