Thank you for all the great information. Yes they are sealed tight. I guess the dark brown on top worries me but you had that as well? I did follow the instructions to the tee as far elevation and timing and such.
I used my pressure canner for the first time to can ground turkey. After several months this is my result and I think it doesn't look safe to eat. The top is dark brown. see pics. What do you all think is this normal or not.
