Sugar is the next tobacco, without a doubt, and that industry should be scared. It should be taxed just like tobacco and anything else that can, frankly, destroy lives.

I think authenticity is important whichever homeland you're from but one of the lovely things about British cooking is that we adopt great food and dishes from all of the lovely people who come from overseas to live in our country. We're a magpie nation - we take the best bits of other cuisines and embrace them as our own.

My aim is to achieve sustainable change, not just make a cute little makeover.

I love roasting because you can give it love, get it in the oven and go and play with the kids or whatever you've got to do, and then hours later you've got a lovely dinner.

My general rule is that if everyone knew how to cook fresh produce from their local area, and Monday to Thursday within 20 minutes, you know, there's millions of recipes out there to be had.

Like most of the other teachers, I'd done a bit of teaching and we all think we're great at what we do, but you realize that normally you have an audience who are all onside, who all want to listen.

Cooking is the ultimate giving!
