On Friends, there are frequent references to Monica's cooking. As I think back, most of them seem to be negative. "Monica's cheesecake is dry and peely", "At least all my songs don't taste like garlic", "Push the duck. If they don't eat it, you will, and it's not very good!", "Tiny portions of pretentious food", And the episode with the bad review, the episode where Janice sends the chicken back over and over, And the episode where they are trying to decipher the chocolate chip cookie recipe, she puts down Phoebe for not detecting nutmeg (which there wasn't so Monica was wrong)
I'm wondering if it was supposed to be a running joke that Monica's food was bad, or if these are just offhand comments not too be taken too seriously? Most of these references are in later seasons, so it could have been something the writers had decided to play on.
