Does anyone know where to find the recipe? (if there is 1)? I've found a load of random ingredients but not sure what else I'm needing. Not sure what I've used so far as it doesn't tell you what you've already added (and I don't want to spoil). He says he doesn't know what book he needs, and I checked the chef's room and there's no recipe in there.
Also how do you get rid of Harry?
