I wouldn’t want to suggest all cooking for one or two must necessarily be of the impromptu, quickly-thrown-together kind (and I say this as someone who is eating a Laughing Cow and plastic bread sandwich as she writes; very delicious it is, too). I don’t mean it should be elaborate and minutely organised, but that cooking for two can be out of the ordinary in a way that a dinner party, unless you really are fabulously extravagant or very rich, just can’t. The solitary diner can sometimes, if not often, eat lobster alone. I buy it cooked and cold and I fry some bacon to eat with it. I might make mayonnaise. I don’t mind what I have to do to it or how I eat my lobster: salad, club sandwich (toast some brioche, just see), as it is in my fingers. The pleasure lies in the solitary indulgence.
