I read the other thread and visited both the guy in Gadgetzan and Ironforge...I'm lvl 39 with 225 cooking. One person said it was a quest you get at 40, another said you can get it at 35. Anybody have any idea what's going wrong?

Correct information might be handy..
The Quest is called "Clamlette Surprise" & is available from Dirge Quikcleave, he is located in the Inn at Gadgetzan.

Pre-bought the listed mats & went to find they are Wrong!!

you need:

12 x Giant Egg
10 x Zesty Clam Meat
20 x Alterac Swiss
