Okay, so, I have no idea what happened but I grated carrots for my carrot coconut cake and they were perfectly fine, then when I went to cut teh tops off to decorate, I noticed some of the carrots looked green on the ends. What the heck! It looked like green coloring fell in. Has anyone had that happen before?

The article about carrots turning green in cakes is really interesting. I've never seen that happen with carrots, but I've seen many loaves of banana bread with green walnuts. 
Thanks for sharing the info.
Wow. I'm glad that I read this thread. I've never had this happen but there's a first time for everything.
