A Bonn diary

Sir: Either Bonn is not the place it was or Malcolm Rutherford, who complains that German eggs crack when boiled (16 Aug- has failed to exploit one of its most civilised amenities.

Ten or eleven years ago I bought in Bonn a gadget called an Eipick—a spring-loaded needle which punctures the big end of the egg ('An der breiten Seite einstechen') to let out the expanding air which would other- wise crack the shell. It's very simple and very efficient. It now costs about 60 pfennig and has made its way to England.

If Mr Rutherford buys an Eipick he will, I promise, be able to look every boiled egg in the face.

Birmingham 17 Sir: Would you please tell Mr Malcolm Rutherford (16 August) that Dutch eggs behave like German eggs with regard to the too thin shells (lack of calcium in the food!). The remedy is to pour some vinegar into the water, or some salt, before putting in the eggs—and he will have no more trouble. (If the cause of the ailment is the same, that is.) And in any case to put the eggs in the cold water and let them heat to boiling point in the water while it is being heated; count the boiling time from the time the -water is really well boiling, not just be- ginning to boil.
