When you've done something quite cerebral. Cooking is sensuous, too. Your novel is quite sensual. It's important to me. It's important to actually write a novel that's about people, which not all novels are.
Some novels are just about voices or a landscape.
But I've got people in mine. Then they have a sensual experience of the world and I want to make that real to the reader, if I can. And that's important, because it makes you write better. To slow myself down, I try and get into the skin of the person or the place or the food and really convey the sensual reality of it. So it's for technical reasons, as well.
