I've got a confession to make. I can't boil an egg. I don't mean that I can't cook, because I can. I mean that I can't boil an egg. I was born just after the end of the Second World War when food was not particularly plentiful and some of it was still rationed. My father reached an agreement with someone who kept hens that there would be an exchange of surplus eggs for my father's surplus home-grown vegetables. Unfortunately the only feed that the hen-keeper could obtain was fish-meal with the result that the eggs tasted of fish. I was made to eat one of these every day as my breakfast.
