I came across this annual report, titled “Well Done” for the food company, Podravka. From the moment you are handed this report it starts to tell the story of food. Wrapped in aluminum foil is a large book containing a smaller book, the heart of the brand. The type on the pages of this smaller book is heat activated and not visible until you cook it!

“To be able to cook like Podravka you need to be a precise cook. That is why the small Podravka booklet is printed in invisible, thermo-reactive ink. To be able to reveal Podravka’s secrets you need to cover the small booklet in aluminium foil and bake it at 100 degrees Celsius for 25 minutes.”
