This reminds me of a story my dad told me. His school went on a field trip to an ice cream factory and he was, of course, expecting this to be the best day of his life. What he discovered, though, left him mortified. They were taking poor-selling flavours and running them back through the machine to change them to something better. If you buy some store brand chocolate and it has undertones of mocha, now you know why. I think of this now whenever I see a product that "may contain peanuts". Like they're not sure.
