Rejected M&M's Flavors

M&M's has certainly taken some flavorful risks — a few calculated, (coffee, pumpkin spice, and now caramel filling) and a few out of left field (jalapeño, butterscotch, and candy corn). But just as Thomas Edison famously needed a few hundred tries before inventing the lightbulb, I'm pretty sure the Mars, Inc. R&D team pitched a few flops to focus groups. Sure, caramel seems like a natural choice now, but it took M&M's nearly two years to get them into our hands. What rejected flavors could they have possibly been considering? While we may never be privy to any of the closely guarded trade secrets and confidential innovations of America's favorite bite-sized candy company, there's no doubt some awful ideas like these were probably tossed in the wastebasket.
