Pink slime is only ground beef carried to an extreme. What you get isn’t “ammoniated” any more than the cookies that are commercially baked with ammonium bicarbonate leavening. (Whose practical use is pretty much restricted to tightly controlled commercial baking processes. Home ovens don’t always succeed in driving out the ammonia and the result comes out as nasty as you’d think.)
We don’t buy commercial cookies either. Most have trans fats up the wahoo in them. I make them from scratch. Better anyway. That way I can reduce the salt a bit if I want or lower the fat a little.
