Pilgrim's Bounty

This is the time of the year where Food and Glory coincide. Yes, it is Pilgrim's Bounty again, the WoW world event that mirrors Thanksgiving. While the reason for it is completely negligible, it is one fantastic event to get your cooking skill up. You can buy a series of recipes at the festival, along with the ingredients for them (except the turkeys, which you'll have to "hunt"). These recipes will get your cooking skill from 0 to roughly 340 in an efficient and ridiculously cheap manner.
One important thing to remember is that some of the ingredients can only be found with specific festival vendors.
For the potatoes, go to Darnassus or Thunder Bluff.
The cranberries can be bought in Ironforge and Orgrimmar.
The pumpkins are sold in Stormwind and Undercity. You will also find the turkeys in Tirisfal and Elwynn.
You should buy 60 or 70 of each before you move on, since there are 60 skill-points between the recipes, and they turn yellow for the last ten points. Nothing is more annoying than having to go back to Darnassus because you're missing two potatoes. Also, since you need around 70 turkeys anyway, you might want to give The Turkinator a shot. After killing each turkey, you have a 30 second window to kill another one. Kill 40 turkeys in a row, and become a turkinator. I would tell you to go places where there are few other people trying to accomplish the same thing, but the fowl only appears in Elwynn and Tirisfal, so your best bet is to try it at three in the morning.

So, I just leveled my rogue's cooking to 350. 'Tis the season.
