Well, so far we’ve seen a couple of the cooking dailies hit the live realms, and as the info I’d provided so far seems to be popular, here’s a bit more info:

The quests are given by The Rokk (<Master of Cooking>) in the Lower City, at around 61,16 coordinates. He gives a new one each day, which changes when the daily quests reset. Here are two known quests so far:

Revenge Is Tasty
Requires 1 Giant Kaliri Wing (drops off Monstrous Kaliri at Skettis, a quest item so you can’t farm for them in advance) and 3 Warp Burgers (made with 1 Warped Flesh each, which drop off Warp Stalkers in Terokkar at a 50% rate and Warp Chasers in Netherstorm at a 25% rate). Combine the Giant Kaliri Wing and the Warp Burgers in the cooking pot provided, and turn in the resulting Kaliri Stew.

Super Hot Stew
Requires 1 Crunchy Serpent and 2 Mok’Nathal Shortribs, which are made with meat from windserpents and raptors, respectively, in Blade’s Edge Mountains. Once you have the two components, go to Forge Camp: Terror in Blade’s Edge and kill yourself an Abyssal Flamebringer; stand over the body and use the provided cooking pot to combine the Crunchy Serpent and Mok’Nathal Shortribs into Demon-Broiled Surprise. Turn in the Surprise to complete the quest.

There are at least two more possibilities for the daily quest; I don’t have details on either of them yet. I’ll post again when I’ve seen them.

The cooking dailies require 275 cooking to complete; I haven’t yet checked to see if they also require level 70. The two quests listed above both require access to flying-mount-only areas (Skettis to get the Kaliri Wings, Blade’s Edge Plateau to kill the Abyssal Flamebringer), but a sub-70 character summoned to the area may be able to do them.
