Takeaway or sit down fish and chips have been part of the British diet for well over 100 years and it is thought that mushy peas were introduced to the dish as an accompaniment in the 1970's. However, peas have long been dried like other pulses, so that they can be eaten all year round. Traditionally, yellow split peas were cooked to a smooth mixture and known as pease pudding. It was often served with pork or boiled ham.
