So wrote Socrates. Inexplicably, his thoughts on pizza are not recorded. But he almost certainly took the same view about pizza as he did about life: the unexamined pizza is not worth eating. On this blog, I’ll be taking a leaf out of Socrates’s book, by systematically studying the different factors that go into making pizza. I’ll report a series of experiments conducted in my state-of-the-art food laboratory, designed to refine and improve pizza making, one step at a time. Each experiment will involve the manipulation of a single factor – be it an ingredient or a procedure – in two batches of pizza. These pizzas will be identical, apart from the single factor the experiment is investigating. In other words, with all other things being equal. It’s good scientific practice, and it’s also an extremely twee name for the blog.
