Why food is a poor instrument of shipboard punishment

What meal would an angry captain serve to punish a crew for poor performance?

Food should not be used as punishment because it is central to morale, and collective penalties are poor discipline.

The panel invents intentionally unpleasant meals, including hardtack, disliked rations, and deliberately meagre servings. The offal example depends on period: brains and other organs are described as familiar food for poorer people and sailors up to around the nineteenth century. After the joking proposals, Dr. Clarke says that interfering with food would never be his preferred punishment because meals matter too much to morale. He also rejects collective punishment. The serious conclusion concerns the effect of provisioning on the crew, rather than which meal would be most unpleasant.
