I know every movement of my kitchen.

The traditional roots of Scandinavian cuisine are not that spectacular, to say the least. When we write about the traditions that we are inspired by, it's more techniques like smoking, preserving. Many of them are not made to make food delicious; they're just around so that you can make food last through the winter. There isn't a great deal of tradition to tap into.

When people are grownups they're grown ups. They make their own decisions you know.

That's how people make sense of a meeting: they eat something. If they were in a sad moment it would be the same thing, they'd be eating something. It's what makes life fun. We don't need it to be delicious or great or all these things if we're just to survive. But it's one of those things that makes life fun, livable. And the more I submerge myself in it, the more fun I seem to have.

21 years ago when I started cooking, to be a cook meant that you were going to stay in the basement. Being a chef, you would never be on a book tour. You could never dream that 20 years later on you would be on a book tour. It wasn't a part of your dreams because it was just totally unrealistic. When did cooks - restaurant cooks, not cooks that have 15,000 television shows - when did cooks become part of pop culture the way they are?

I started to change. It was sort of a restaurant mid-life crisis, you could say. I lost a lot of confidence, not so much as a father or as a friend, but as a boss, as a chef that's to make decisions throughout the day all the time. I just slowly started burning out. Once you lose your confidence like that, you start being angry in the kitchen. I couldn't recognize myself anymore. I started writing the journal. It was never meant to be a book, but the editor at Phaidon read parts of it. As editors do, I guess.

I just love this idea of using, especially in terms of food, using that common sense. If you follow that - it's hard to talk about it without sounding like some New Age idiot, which I think is a bit unfair - but, if you do follow that natural cycle, you will inevitably eat better, cheaper, and much, much, much, much healthier.
