You never know when some small thing will lead to a big idea. Travel is very inspirational - but it's in the ordinary that I find my themes of love and work and family.

The 'Story of Silent Night', which was given to me one Christmas when I was six - it was the story of a down and out composer who had no ideas left, and it was Christmas, and he came up with the hymn 'Silent Night.'

Food is so important - it sustains us, it provides a social focal point, and it is fun. I cannot unravel the difference between love in my family and the preparation of food because they are so closely woven.

There is no one on earth who knew you from the day you were born; who knew why you cried, or when you'd had enough food; who knew exactly what to say when you were hurting; and who encouraged you to grow a good heart. When that layer goes, whatever is left of your childhood goes with her.
