Cooking outfit

Chef

Roleplaying outfit that will make you resemble a cook.

Hat

•  [Chef's Hat] - BoP, Vendor (100 [Epicurean's Award])

Main Hand

Rolling pin

•  [Rolling Pin] - BoA, Vendor (50 [Ironpaw Token])
•  [Cookie's Tenderizer] - BoP, Drop (The Deadmines (normal only), "Captain" Cookie)

  This item is one-handed mace, so only  Death knights,  Druids,  Paladins,  Priests,  Rogues,  Shamans, and  Warriors can wear it because of class weapon proficiencies.

  It is not unique, so pair of them can be dual wielded.

  Heroic version of tenderizer has other model (it is not rolling pin).

Frying Pan

•  [Frying Pan] - BoA, Vendor (50 [Ironpaw Token])

Meat cleaver

There are two types of meat cleaver in game - clear and blooded. All of them (except one) are main-hand or one-handed axes, so only  Death knights,  Hunters,  Paladins,  Rogues,  Shamans, and  Warriors can wear it because of class weapon proficiencies.

•  [Meat Cleaver] (blooded) - Drop
•  [Cleaver] (clear) - Vendor
•  [Neurosurgeon's Tool] (blooded) - Quest. Attention! This meat cleaver is dagger: so if you are  Druid,  Mage^†,  Priest, or  Warlock^†, do not miss it.

  † - especially for these classes, because they could not wield  [Cookie's Tenderizer] as alternative in their cooking sets.

•  [Hacking Cleaver] (clear) - BoE, Drop
•  [Abomination Cleaver] (blooded) - BoE, Drop (Dr. Whitherlimb - rare mob in Ghostlands)
