Nice biscuit

A Nice biscuit is a plain or coconut-flavoured biscuit. It is thin, rectangular in shape, with serrated edges, lightly covered with a scattering of large sugar crystals and often with the word "NICE" imprinted on top in sans-serif capital letters. It is often served as an accompaniment to hot drinks, such as tea. The name probably derives from the city of Nice in the south of France. 1929 editions of the Hull Daily Mail carried an advertisement for Huntley & Palmers Nice Biscuits using the phrase "Delightful as the town after which they are named", indicating that by this point their manufacturers intended the public to associate the biscuit with the French city, whether or not that had been the intended pronunciation.
