Kit Kat is one of Britain’s longest-lived chocolate bars – on sale since 1935, and now sold around the world.
But there’s one mystery that few have stopped to ponder until now – what exactly IS that stuff in between the wafers inside a Kit Kat?
In BBC Two’s Inside the Factory, Gregg Wallace went behind the scenes at the York factory to discover what’s actually inside.
Basically, the bit in between the wafers is made of ground-up broken Kit Kat bars from the same factory.
A worker tells Gregg, ‘They go into re-work, where they’re used for the fillings for the wafer.’
The bar was first created by Rowntree in 1935 – on the suggestion of a worker at the Rowntree’s plant, who suggested a bar which workmen could carry in their pack.
The first Kit Kats were called Chocolate Crisp, but were rebranded shortly afterwards as Rowntree began to use the ‘Break’ marketing slogan.
The first Kit Kat bar – and the original – is the four-finger version.
