I am not one of those people who go around photographing the food on their plate - at least, not very often. I have been known to snap the odd snap when I have been lucky enough to be in a fashionable restaurant. But I couldn't help admiring the colour of the yolk in my boiled egg at breakfast. The chicken who laid this egg lives on the farm just behind our cottage. No food miles involved here, and the richest orange yolk I have ever seen!
