I've just brought home a very old large copper pan with tin lining that doesn't appear to have been used for many years. There is only one small line of copper visible, so I think we're OK there (for now- I'll have it re-tinned when needed). So my questions are all about the interior of the pan only.
I have thoroughly hand-washed the interior with liquid dish soap & water a few times, so it seems clean. Is my next step to boil some water in it? Or...?
Also, I noticed that as I wet the tin lining, some spots darkened, as if they were porous. This concerns me a bit, as my other tin lined pan does not do this. Could this be from some "incorrect" cleaning method by a previous owner? Is it safe to cook in or is there something I can do to remedy this? Or is this normal for aged tin and perfectly fine? (my other pan's lining is fairly new)
Any input is greatly appreciated. I'm hoping to use it tonight, but I'd also like to wake up tomorrow feeling well!
