I was at the store the other day and noticed that they had a limited edition Thin Mints-flavored Nestle Crunch, based on the classic Girl Scout cookie. I had to pick it up. But when I looked at the ingredients, I was in for a surprise:

Ground peanuts.

Why they put ground peanuts in the Crunch/Thin Mints mashup, I couldn’t say, because peanuts aren’t in either Nestle Crunch or Thin Mints. (Not on purpose, anyway, though they do list a cross-contact warning.) And nothing in the packaging except for the ingredients and allergy statement makes any mention of it. The candy bar isn’t labeled as Crunch + Thin Mints + Peanuty Goodness, it’s just labeled as Crunch + Thin Mints.

This is why clear labeling is important: I would never have expected to find peanuts in a combination of two things that don’t have peanuts in them.
