Just a quick update on the tongue. It's been four days since it went in the brine, and there is a startling change in its colour. It seems to have turned purple, almost like it's been sneaking into the freezer and getting friendly with a grape popsicle.
I guess that makes sense, the brine is really salty and the blood in the tongue is being drawn out making it seem more purple. The brine itself has taken on a pinkish colour, which I suppose supports my theory. Now I've never done this before, so if there is anybody out there who can give a more detailed explanation as to why my tongue is purple I'd be much obliged.
The tongue will be going into the pot on Wednesday for its nice long boil, more then.
