Duchess Bakes a Cake

A long time ago there lived over the waters, A Duchess, a Duke and their family of daughters. Everything went smoothly and happily in this large family, until one day the Duchess decided to make: A lovely light luscious delectable cake. Would she take the cook's advice? No, she would not. The Duchess put many things into the cake, adding the yeast six times for good measure. So the cake rose, and the Duchess with it -- and how were they to get her down again? It is Gunhilde, the youngest of the daughters, who suggests a happy solution.
