Nigella Lawson provides a step by step guide to creating delicious recipes for every occasion, be it cooking for many or for those times when you are home alone. For Nigella entertaining means sharing time with friends, not spending hours slaving over a hot stove and the taste of the food is far more important than agonising over presentation. Today she tackles creating delicious food in a very short space of time. On the list are lemon linguine and chicken with couscous and a delicious chocolate dessert.
