Sift the flour and work in the slightly softened butter. Cream the yeast with a teaspoon of the sugar. Mix flour with the eggs, yeast and enough milk to make a light dough. Leave to rise, covered, in a warm place for about thirty minutes. Then work in the sugar and spice and form into flat bun shapes. Let rise for fifteen minutes, then bake at 425F (Reg 7) for fifteen minutes.
