A Cornish Fairing is a spiced biscuit/cookie, originating from Cornwall. The word fairing referred to an edible treat sold at fairs around Britain, but came to be known synonymously with the ginger biscuit. The ginger flavoured cake or biscuits were first sold at fairs in the 11th century, and continued into the 18th century. According to Wikipedia, a fairing can mean cake or biscuit, and was also offered as a love gift.
