I was forewarned about the open stating of the answer (You oughta do things like that in yellow or white, nuncle to give us latecomers the fun) so I didn't scroll down and I guessed 'dough' (or actually, 'bread'), too. The racy answer requires the two 'things' to be different which it certainly looks like they're not in the modern English. My OE isn't near good enough to tell if that's the case in the original.
