I have this big 'ol 6 gallon lobster pot. Its black and probably galvanized steel. Can I use it for the boil? I know stainless steel is usually recommended, so I'm wondering if using this pot could cause any problems.
Stainless steel, aluminum, or enamel (if it's in perfect condition). I don't know what you mean by galvanized steel... Are we talking cast iron or something? If it's porous like cast iron, I wouldn't bother with it.
I made the mistake of boiling crab legs in my brew pot once. No matter how I cleaned it, I couldn't get rid of the seafood odor. It would seem fine when I cleaned it, but as soon as it got hot, the smell would come back. I finally got another pot and delegated the original to crab boils. My pot was an aluminum turkey frying pot.
