In the UK in 1981, Hedgehog Foods Ltd decided, as a joke, to produce Hedgehog flavoured crisps (potato chips). To everyone's surprise, the crisps were a huge success.
Hedgehog flavoured crisps were actually flavoured with pork fat and no hedgehogs were used in the manufacturing process. Consequently, it wasn't long before Hedgehog Foods Ltd was in court (1982), up against the Office of Fair Trading, on a charge of false advertising.
Bizarrely, a settlement was finally reached when Mr Lewis, of Hedgehog Foods, interviewed gypsies who actually did eat baked hedgehogs, to ascertain the flavour of hedgehogs. Mr Lewis then commissioned a flavourings firm to duplicate the flavour as closely as possible and changed the labels from "hedgehog flavoured" to "hedgehog flavour" and all interests were satisfied!
