When I did 'Battlestar Galactica' it was the first time I really understood science fiction. That was a very political drama but set in spaceships so people didn't really take it seriously. But some really fascinating things were explored in that.
What I've enjoyed most though is meeting people who have a real interest in food and sharing ideas with them. Good food is a global thing and I find that there is always something new and amazing to learn - I love it!
