Canned Chicken Lid with Black Stains
While canning chicken, I processed 19 pints for 75 minutes and when I got them out of the canner, 1 jar had black stains on the lid and I was able to wipe off the lid with a wet paper towel. Most of it came off, but stains remain on the lid.
There is no rust on the inside of the ring. Are all 19 pints of the chicken I canned ruined?
These were newly purchased jars. I washed the jars and lids/rings; and I soaked the lids/rings in hot water while I filled my jars with the chicken.
Could it be that I simmered the lids/rings in a stainless steel pot too long? They were simmering while I filled the jars with chicken and I had to take a little time to get all 16 jars filled.
Please help. Have I ruined my canned chicken?
