Put sugar and salt in mixing bowl, pour on scalded milk. When lukewarm add dissolved yeast cake and one and one-half cups flour, beat thoroughly; cover and let rise; when light add melted Cottolene, well beaten eggs, grated lemon rind and just enough flour to knead. Cover and set to rise again; when light turn on a floured board, knead slightly; roll to one-half inch thickness, shape with very small biscuit cutter, then roll each biscuit in the shape of a finger roll. Place on a buttered sheet an inch and one-half apart; set to rise, and bake fifteen minutes in a hot oven. Five minutes before removing from oven, brush over tops with white of one egg slightly beaten, diluted with one tablespoon milk.
