Hand in ingredients in request order
The quest asks for Spider Cider, Dust, then Raw Turkey. Return to the Haunted Kitchen after each request. Having later ingredients in your inventory does not replace the current hand-in.
Where the quest sends you
Spider Cider is behind the Quiz Noob’s room challenge. Dust is in the Black Bedroom upstairs. Raw Turkey comes from the Turkey encounter in the Catacombs. Follow the room names if dialogue directions are confusing; the reference flags a left/right error in the Turkey directions.
What you receive
Completing the quest gives Ghost Potion and access to his cooking service. The Cookbook later expands cooking to two ingredients. The Chapter 1 Blackrock Castle bottle incident is a separate story event, not a combat unlock.
