I had a note by my computer screen with the colours from the brief: red, pink, summer orange, gold, paperbag brown, no black. The colours make a feeling and you take that feeling and turn it into a picture.

And they’re delicious colours. They make food look good. 

In the introduction for the book, you’ve written that if Pipi was a cake, she would be this glorious towering sponge cake. If you were a cake, what would you be? 

If I was a cake, I love the idea of a tall wobbly sponge and defying all odds.
