Can something be "new" if it's made with "old" ingredients?

BANTER BITE BACKSTORY: Black's fascinated by the business and marketing aspects of food mash-ups (especially the multi-generational angle), while Red's excited that her beloved Dunkin' has collaborated with Post Cereals and there's now Dunkin' cereal (and both of us love the tag line, "Now you can have your coffee and eat it, too!). Funny thing is that we've all probably been doing our own "mash-ups" for years (ok, maybe not Black).
