UK's rival to the Tim Tam can no longer be called chocolate

In short:

The UK's rival version of a Tim Tam, the Penguin, is now labelled as "chocolate flavour" because it no longer meets the UK's definition of chocolate.

Rising cocoa prices have led to some manufacturers changing the recipes of chocolate products to the point they can no longer be legally defined as chocolate.

What's next?

Tim Tam maker Arnott's says it has no plans to change its recipe. Cocoa commodity prices are starting to fall but retail chocolate prices are expected to remain high for some time.
