Ask people to name their most hated vegetable and it's generally agreed that the answer will be sprouts, yet annual sprout sales in the UK are worth £35m. That's allegedly 47,000,000 units of distress purchase and judging by the supermarket tonight, most of them are bought this week.
It's not the season of masochism, so why the paradoxical behaviour? Because people have bought a story that convinces them that sprouts say Christmas like no other vegetable. Because people can joke about them and because people see other people doing it.
