I have dug out an old pressure cooker - unused for years and the aluminium has gone rather black.
I was wondering whether to clean it up and use it again to make bone broth, but am worried that even if I keep the lid off to skim it during the first 15 minutes after it has come to the boil, what will happen if scum forms after I close the pan and set set it to High Pressure?
If anyone out there is making bone broth in a pressure cooker using raw or cooked bones, how do you deal with this please?
