My own preferred fitness regime is to use my bicycle.
Baking can be done with a few simple ingredients, so it's about simplicity and nostalgia - people are reminded of their childhood.
I love the sensation of being out in the open air, far away from all the distractions of modern life. I will usually disappear for a couple of hours, and that time on my bike is quite sacred, as it's when I do all my serious thinking. Sometimes I will stop off at bikers' cafe and have a bacon sandwich.
One day, I'll disappear and hide in a corner of Britain. I'll own a bakery in a village, live above it, have a big garden because I like mowing. I want to get up when I feel like it, let people queue for my products, and when they're gone, shut the shop and think about tomorrow. Creating magic - that's my dream. And I'll do it.
You can't beat a good doughnut. It has to be a jam one with light pastry and caster sugar on the outside. If I'm really tired, I have to hunt one down, because it gives me that sugar rush to keep me going.
The sugar tax is fine. I agree with that. But I think it probably doesn't go too far. But then, I work on 'The Great British Bake Off.' We make cakes with sugar and butter. I can't be too critical. It is like anything in life: it is all about moderation.
Some people seem to think their oven self-cleans, but you need to clean it to stop things getting blocked up so you get a good rotation of air and heat inside. Get a probe to test the oven is reaching what it says it's reaching too.
To make a full-blooded puff pastry, you need time, you need patience, and you need precision. It's all about the lamination: it's all about building up the layers of butter, dough, butter, dough; as the butter melts, it creates steam, and that brings up the layers of the two doughs apart from each other, and that's what gives it the rise.
Years ago, I saw a job for head baker for The Dorchester Hotel in London, and I didn't want to move away from the North West. But then I thought, 'I've got to do this for my career,' because I was very ambitious. So I went for it and got the job.
I want to pass on my secrets to people who are going to say, 'I have realised that I love baking, and now I'm going to make my bread and sell it at the local farmers' market,' or who might say, 'I am going to use the local Post Office in our village to sell my cakes.' I want to give them that little bit of fire.
Naples is curiously chaotic and, if I'm honest, a bit dilapidated. It certainly has a 'lived-in' look. It's alive, it's vibrant, it's a little bit dirty, it's busy, and I loved it. I felt like this was how Rome would probably have been 2,000 years ago. There's a real bustle, and it's down and dirty.
