A MARINER from a marinade?
I don't really deserve the praise, Soriman. I guessed we needed VALLEY because it uses a lot of the same letters as WHALEY, plus the V from flavorist, then looked up other names for the Imlad Morgul, thinking of what other letters we needed.
I did, however, google Whaley and flavorist before any of this, and came across a scientific document about fruit and vegetable flavours, and looked without success for a Dr Whaley in the credits!
