Almost like vanilla, but more earthy.
Come to think, I had a friend that had a block of real amber. It reminded of me of play-doh with vanilla added to it, in fact, the block itself was kind of doughy in texture. I can remember her picking it up, inhaling and exclaiming; "I LOVE this, it smells like cake!" The neat thing about it was that you could rub it on your wrists and it would stay on for two days.
