Via Dezeen Magazine and BoingBoing, we hear of a design firm, the Croatian team of [1] Bruketa & Zinić has pushed the envelope (though it be foil) in thematic annual report design that actually has to be cooked to be read.

The report, Well Done was created by them for Podravka, a leading food industry concern in southeastern Europe. The small book itself comes in a bigger book, with facts and figures.

To reveal the content in the smaller book, first it must be wrapped in foil then bake at 100 degress Celsius for 25 minutes’s time. After that, the ink on the blank areas of the pages will appear, revealing many Podravka recipes and illustrations of the dishes.
