The story of the chip goes back to the 17th Century to either Belgium or France, depending who you believe. It is thought that the chip may have been invented as a substitute for fish, rather than an accompaniment. When the rivers froze over and nothing could be caught, resourceful households began cutting potatoes into fishy shapes and frying them as an alternative.
Around this time Jewish refugees from Portugal and Spain were introducing the idea of fried fish to Britain. This fish was mainly sold by street sellers who had large trays hung round their necks containing the fish. In fact, Charles Dickens in Oliver Twist (printed in 1837) refers to an early fish shop or “fried fish warehouse” where the fish mainly was served with bread or baked potatoes.
