@Fido,
Dont worry, old biscuit dough(past any expiration date and several months in the freezer), need not be a waste. Whenever we find some food articat that had slipped into a freezer cravasse, we would take it out, inspect it, then
say for biscuits, bake em off as chunks with some gralic powder (The dogs love em as treats) Also partially baked to a leather hard styage, they serve as good wired fish baits for deep sea fishing. One of my best flounder rigs has a series of "baskets" that hold tiny chunks of slightly baked bread or rolls. The flounder love the essence of yeast and will start a frenzy (dont tell anybody but this is a big secret to catching big 'Alibutts. "Alibutts love a yeast flavor and will swallow the whole rig (which can be a problem retrieving from a two foot gullet)
