Charles Martell began making Stinking Bishop cheese from the milk of his herd of Gloucestershire cattle, to increase awareness of the breed, which had previously been near to extinction. Made famous by the Wallace and Gromit films, the pungent smell of the cheese is in the rind, which is washed in perry made from the Stinking Bishop variety of pear. The bacteria in the perry cause the stink, but the flavour of the cheese is surprisingly more delicate (particularly if you hold your nose!). The milk is pasteurised and vegetarian rennet is used.
