Savory Deviate Delight - Gold For Levels 14+
Yes, the cooking skill can make you WoW gold. Witness this time-honored gem: Savory Deviate Delight.
To get the Savory Deviate Delight recipe, you need merely make sure to kill as many things as humanly (or orcishly) possible in the Barrens. By looking at the drop rates, it appears your best bet is to farm Greater Plainstriders and Theramore Marines (which are green to Alliance, so only farmable by Horde). Both of these mobs still only have a very slightly better drop rate than any other mob in the Barrens; a drop rate of about about .1%. A fun mob to grind for this are Muck Frenzies (68,48). These are located in an weird underwater tunnel on Fray Island.
After learning the recipe, you need merely cast your fishing line in any of the water in or around the Wailing Caverns to get Deviate Fish. For some more details on the best fishing spots see this comment. Also, if you are Alliance and on a PVP realm, you will want to fish within the instance to reduce your chances of getting ganked to zero.
Though the market on these fluctuates, you are always certain to get a couple gold out of them from the auction house. If you get lucky with the recipe drop rate and are able to farm more than one of the recipes, you can sell those for quite a lot of WoW gold as well.
Factoid: Two of the costumes you can receive from eating the Savory Deviate Delight are either a pirate or a ninja. The pirate costume is called %26#8220;Yaaarrrr%26#8221; and the ninja costume is called %26#8220;Flip Out.%26#8221; These come from the underground comedy website Real Ultimate Power, of which someone at Blizzard must be a fan. But then who isn%26#8217;t a fan of guitar-wielding, pirate-bashing, hippopotamus-befriending ninjas?
