Playing Russian roulade with a meringue utan

Russian roulade.

A dinner party game for six people. After the main course has been consumed, and the host realizes that only five coffee cups are available, a tough decision is made.  The dessert - a golden brown roulade of baked, sweetened, whisked egg whites, cream and raspberries, known colloquially as a meringue utan - is divided equally into six portions and served. One of the portions is laced with a fatal* dose of cyanide, and the problem of the coffee cups is solved.

*please ensure that your party guests do not include Grigori Yefimovich Rasputin, or your coffee cup problem may remain.
