It's all about leveling it fast and cheap but it's probably the best one out there.

The cooking is much like the rest of the crafting. You start out with basic mats and refine them up to a usable item but it emulates IRL cooking in that you make raw materials into something else in between and then use those to get the usable item... Basically just extra steps. It seems really daunting at first but you get the hang of it pretty quickly as you do it.

As for acquiring the ingredients, either through gathering, trading post, or karma vendors. Cooking is the only one with a heavy reliance on karma vendors.
