The Northrend Gourmet has been a hot topic achievement since Northrend hit live realms, because it simply wasn't possible. Four of the required recipes were completely missing. As of the current PTR build, that's no longer true. Two of the recipes have been re-added to the game, and two recipes have been wiped out of existence. Not added to the game, but no longer an achievement requirement either.
Shoveltusk Soup and Succulent Orca Stew were the two that didn't make it back into the game, which makes one of 3.0.8's patch notes make a lot more sense. You know, the one about Shoveltusk Meat being converted to quest items? And orcas are just Chilled Meat fodder now, it seems.
