One of the strangest wallpaper concepts, initially depicted in a wildly popular children’s book was brought to life thanks to the mix of expertise from a wallpaper specialist and some of the most widely acclaimed chefs in the world.

In the 1964 Roald Dahl book Charlie and the Chocolate Factory as well as its very popular film adaptations, lickable wallpaper was one of the many unique and elaborate edible delights created by the enigmatic candyman Willy Wonka.

Whilst initially designed to be purely fantastical, there have been several chefs that have actually managed to make a real version of it.

One appeared in the book Roald Dahl’s Revolting Recipes, which involved jelly mix and over eight hours of drying and simmering, the result being closer to a thin sheet of apple than wallpaper itself.

McVities spent a month lining one of its office lifts with components from over a thousand Jaffa Cakes, creating a fascinating lickable wall installation as a marketing campaign, directly inspired by the Charlie and the Chocolate Factory book.

Probably the most famous example of this, however, was made by the eccentric experimental chef Heston Blumenthal.

For an episode of his show Heston’s Feasts, Mr Blumanthal was tasked with making a 1960’s feast inspired by the Charlie and the Chocolate Factory book.

His wallpaper did not have fruit flavours but instead the flavours of tomato soup, prawn cocktail, pineapple, apple and cocktail sausages

His celebrity guest diners were utterly surprised as a result. Part of this was due to the success of the taste itself but the other part was the utter shock that it was actually achieved.

Mr Blumenthal did publish the recipes in one of his books, but it involves 19 ingredients, tea strainers, a food dryer and a stencil to achieve.

Regardless, it is a fascinating example of just how adaptable wallpaper can be, and in a wallcovering world which features light-up wallpaper and wallpaper that can be used to generate power, edible wallpaper seems like a particularly unique delight.
