you see British people are servants. their lord, as the call him or her, as him or her prefers, only alots a certain amount of harvest rub back to the farmers. Being a witty bunch, the peons make the most of their rub. In a traditional sense a pie is exaggerated tart filled with sweetened and gelatinous fruit (cherry is the queens favorite). But for the peasants, the sourness of rot or richness of grub, offsets the sweet taste of a traditional pie. Therefore it is preferred to put any food scraps available into a pie form so as to limit the foul feelings of being poor and gives some sense of value and happiness. This is especially true in the wet months of February when steamed peat and gorse bark is all that is left in the cellars. Hence the term "mud pie", A term given by early Roman explorers.
