Despite Poole’s contempt for the gastro-commentariat (sorry, but this suffix is addictive), food and what we do with it can brilliantly illuminate society, as the historian and food columnist Bee Wilson has shown before. Her new book on kitchen tools and gadgets is full of treasures to savour. There is Hitler’s use of the one-pot meal as an ideological tool, to put alongside roast beef’s historic role as a totem of British exceptionalism. There’s the startling theory that cutlery has changed the shape of the human face, the deep overbite of the Chinese having evolved to help chopsticks into the mouth. Our overbites are smaller, because it wasn’t until 1,000 years later that we deployed knives and forks. And in some primitive societies, front teeth still meet edge-to-edge.
