I cannot "Roast" carrots?

What I expected to happen was...:
I expected to be able to cook carrots, they'd be like Baked Carrots afterwards, I thought.

What actually happened was...:
They didn't react at all

Steps to Reproduce:
1. Put a carrot in a furnace with coal as fuel, or somethin' else.
2. Wait...
3. Nothing happens...

I thought you could cook carrots too since Potatoes could.
