HISTORY OF EGGS
Celebrated since the dawn of time, the egg is a symbol of fertility, creation and new life. Though long considered a springtime food, it has now become an essential ingredient in all of our culinary traditions. The ancient Persian and Celtic cultures celebrated the spring equinox with the gift of red-dyed eggs. The eggs were shared at a meal, and afterwards, the shells were carefully crushed, a ritual to drive away winter. Since the beginning of human time. Wherever eggs could be obtained. Differerent kinds of eggs were/still are eaten in different parts of the world. Ostrich and chicken are the most common. Because eggs are relatively easy to obtain, excellent protein sources, adaptable to many different types of recipes (from simply boiled, fried, or stuffed to complicated quiche, custards or meringue), and fit the bill for meatless fasting days required by some religions. Eggs have been the object of much socio-religious symbolism and tradition. Over time, some groups have encouraged the consumption/decoration of eggs in celebration of certain events. Others have decided eggs are filthy food which must avoided. None of this is arbitrary. "It is likely that female game birds were, at some time in the early history of man, perceived as a source both of meat and of eggs. Men discovered that by removing from the nest eggs that they did not wish to have hatch (or that they simply wished to eat), they could induce the female jungle fowl to lay additional eggs and, indeed, to continue to lay eggs throught an extended laying season." "Eggs have been known to, and enjoyed by, humans for many centuries. Jungle fowl were domesticated in India by 3200 B.C.E. Record from China and Egypt show that fowl were domesticated and laying eggs for human consumption around 1400 B.C.E., and there is archaeoligical evidence for egg consumption dating back to the Neolithic age. The Romans found egg-laying hens in England, Gaul, and among the Germans. The first domesticated fowl reached North America with the second voyage of Columbus in 1493." --- "The egg tracks it name back to a prehistoric Indo-European source related to words for 'bird'...The Old English term was oeg, which survived in Middle English as ey (plural eyren)....But in the fourteenth century the related egg was borrowed from Old Norse. For a time the two forms competed with each other (William Caxton, in the prologue to his Book of Eneydos (1490), asked 'What should a man in these day now write, eggs or eyren, certainly it is hard to please every man'), and the Norse form did not finally emerge as the winner until the late sixteenth century." Birds and reptiles lay eggs. Of these, some are consumed by humans. Preferences vary according to place, taste and economic conditions."Eggs from many species of fowl (birds) have doubtless been consumed since the very beginning of humankind's stay on earth. In historical times, ancient Romans ate peafowl eggs, and the Chinese were fond of pigeon eggs. Ostrich eggs have been eaten since the day sof the Phoenicians,...
