Eating habits in the western world today bear little resemblance to those of our grandparents and those who lived in the earlier part of the twentieth century. The science and technology of food production, processing and distribution has developed dramatically. With the aid of more rapid transport, by land, sea and air, an almost limitless range of food, in greater quantities than ever, from all over the world, is available from retail outlets for home preparation or ‘eating out’ at restaurants, fast food establishments and other food service premises. Less and less food is prepared now from fresh, locally produced basic ingredients as described in the older cookery.
