As a judge, I am having a hard time thinking about seeing a box with just MM in it. It would almost be like seeing a box with just burnt ends.
I guess it would be "ok", but I think a box with other parts of the item would better represent the overall cook, and their ability to cook it.
The rule seemed fine the way it was. Don't think I'll change, but, time will tell (not that I am a major competitor in any catagory, but I plan on getting there
Just my 2 cents...........
