This episode was very entertaining as Bender's dream of becoming a chef is ruined (it's a good thing the crew didn't drink that liquid though). The ending is terrific with Professor Farnsworth declaring that the secret ingredient was merely water... with LSD or "confidence" as Bender prefers the term to be.
The checklist that Bender has is also great and his chef training, including chopping up his arm and accidentally killing his trainer, Helmut.
The B story of Zoidberg framing Fry for breaking the Professor's ship and the obvious clues such as "Fry Confesses" on a pad labelled "From the desk of Zoidberg" and "I hate bottles" on Fry's shirt. The return of the accusing parlour to show that it wasn't a "what if we had an accusing parlour" question was good since it was randomly put in on Anthology of Interest.
Both stories were good but I preferred Zoidberg's.
