The diagram illustrates the way in which frozen fish pies are made their road to the end of the production line. Overall, the ingredients needed to make the pie are peas, fish, sauce, and potato, being put under several processes. In the first stage of making the frozen pie, a delivery truck arrives with potatoes and fresh salmon. While the potatoes could be stored for up to one month before preparation, the salmon is put under the process in under 12 hours. The potatoes are then cleaned, after which they peel them, later throwing the waste. Subsequently, the sliced potatoes are chill after being boiled, after which they are stored. In the second part of the process, the salmon is seasoned with lemon juice and salt, then put into a steam oven. At this point, two workers remove and throw out the skin and bones of the fish. Another employee inspects the salmon and sends it out to be seasoned again with prepared peas and sauce. The previously stored potatoes are being thrown over the salmon, forming the pie. Finally, it is wrapped and frozen, making it ready for storage or dispatch.
