I can't help it, I do love Jamie Oliver. One of Jamie's things in his 30 Minute TV series is to suggest that the prepared dish be served on a normal wood cutting board, right after its prepared. Eg in one eppy he serves a nicely dressed, long roast beef sandwich straight on the board after prepping it with juices dripping on same board. It does look quite nice. But I notice that often, the boards he uses for both cutting and serving look very mouldy in some areas. I'm trying to find a youtube episode with a very mouldy example for anyone who doesn't know what I mean - but you can kind of see a bit of it here, this is the steak sandwich episode - http://www.youtube.com/watch?v=isxKwv... (you can kind of see it at the beginning, and at 13:16 you can see the mould on the side of the board, at 15: 11 you can see the dark patches at the corners).
*Is* that black stuff mould or is it the board naturally darkening? If not, what else is it? If yes.. yuck, right? Shouldn't we be bothered that he's sopped up mould juice onto his foot long? I've seen this kind of black staining on boards of other cooking show hosts - i think most recently i saw an extremely stained board on Nigel Slater's Simple Suppers. I do get that same stuff on mine, and it can't be scrubbed off. I just discard my cutting boards once the black stuff gets to a point (the point is far below what i see on jamie's boards). I have a wire rack for cutting boards that is well ventilated and dry them after use there, but I also do dry them on the dish rack (which is even better ventilated) sometimes. They dry fast. Anyway I do have other issues with boards and prefer to get all new cutting boards every few months. I use both wood and the plastic kinds for different purposes. I don't know what kind of wood my wooden cutting boards are made of. I don't immerse the boards in water.
How often do you change your boards? Do your wooden boards get mouldy?
