It really is worth buying boiling chickens; it may seem more difficult because of the time factor, but, thinking ahead, you can put a nice fat hen in a pot with some herbs and vegetables, cover it with water and put it to simmer very gently while you go out. It can sit there for hours, gradually becoming tender, and it makes large amounts of delicious broth. It is worth going further to find a bird that has had a happy life, but even a battery hen has a remote resemblance to chicken, once carefully cooked. All poultry is now fairly cheap, since it is reared on such a vast scale.
