On the subject of books, and not quite Zumbo, I was in Big W yesterday and saw a book on the shelf called Thermo Struck, it is by Kim McCosker who has all those books, cooking with 4 ingredients.The book was only $10.00, and written to suit all Thermal cooking appliances.I was in a hurry and didn't have time to have a good look. For anyone interested, it was in their book department with the cook books. A bit bigger than a paperback novel. The cover was covered in an Orange & cream colour design, unlike you would expect a cookbook to look.
