Put all these ingredients together into a saucepan and mix together with a wooden spoon for a few moments. Then put onto the back of the stove where it is not too hot, and cook until the mixture has become stiff. Cook a few moments longer, stirring always; then turn out onto a bread-board and spread to a thickness of a finger and a half. When cold, cut into diamonds or squares the width of two fingers. Butter a baking-dish, and put the squares into it overlapping each other. Add a few dabs of butter here and there. Put another layer of the squares in the dish, more dabs of butter, and so on until the dish is full. Brown in the oven.
