With the introduction of several new food & drink related achievements in patch 4.1, I have seen a rise in the prices of almost all the cataclysm buff foods & drinks craftable by my maxed cook. Most notably, chocolate cookies have been flying off the shelves especially when I add a little bark linking the cookie to the new 'You'll feeel Right as Rain' achievement.
If you've been reading my blog for a while, you'll know that my DK sat in SW at lvl 75 for ages. I had no need to level her to 85 for either JC or Inscription recipes but I did do the fishing & cooking dailies on her for the guild rep. However, her cooking skill is maybe 150 so she couldn't really make use of the Chef's Awards until patch 4.1 hit! Yay for Bario Matalli & his bag of Imported Supplies which costs just 1 Chef's Award token & contains 2 stacks of Cocoa Beans (although I have had bags with 51 cocoa beans so there's obviously a proc type thing in there too).
The prices were ridiculous! Some of the vendor bought items were listed for 30-50g each although some were still under 5g each. I smelt an opportunity so as of today, I have had a cook up of all the cataclysm foods I can & have them listed at reasonable (around 10g per) prices for singles. When I logged off last night, they were selling fairly well but with the login servers down this morning, I've been unable to find out just how well :)
So if you have a high level cooking skill & spare chef's awards, what's stopping you? I think this will be one of those markets I jump in & out of 'ninja style'. I'll be keeping an eye on the cookies in particular but where I've been selling the odd ones & twos of cooking mats, I'll cook them up now & sell the food instead. The bonus to that is the Guild achievement Set the Oven to 'Cataclysmic' which, in a small guild like ours, is a long way off for now.
