Fish and chips is a hot dish consisting of fried fish in batter served with chips. The dish originated in England and is an example of culinary fusion, as its two main ingredients were introduced by immigrants. Fish and chips is a common take-away food in the United Kingdom and numerous other countries, particularly in English-speaking and Commonwealth nations. Fish and chips first appeared in the UK in the 1860s, and by 1910, there were over 25,000 fish and chip shops across the UK. By the 1930s there were over 35,000 shops, but the trend reversed and by 2009 there were only approximately 10,000. The British Government safeguarded the supply of fish and chips during the First World War and the Second World War and it was one of the few foods in the UK not subject to rationing during the wars.
