1 cup sugar.
1/2 tablespoon milk.
1 tablespoon melted butter.
1/4 teaspoon salt 1 cup flour.
20 minims hydrochloric acid (CP).
1/4 teaspoon soda.
(This amount of soda and hydrochloric acid is equivalent to 1 teaspoon of baking powder).
Beat egg until light. Add the sugar gradually, then the hydrochloric acid and the milk. Sift the flour, soda and salt together. Add the dry ingredients to the egg mixture. If baking powder is used omit the hydrochloric acid and the soda and sift the baking powder with the dry ingredients. Lastly add the butter. Line the bottom of a dripping pan with paper. Butter the paper and the sides of the pan. Cover the bottom of the pan with the mixture about onethird of an inch deep and spread evenly. Bake about twelve minutes in a moderate oven. Take from the oven and turn out upon a moistened towel. Quickly remove the paper, and cut off a thin strip from the sides and ends of the cake. Spread with jelly or jam which has been beaten until soft, and roll. Sprinkle with powdered sugar and roll in paper to keep it in shape. The work must be done quickly or the cake will crack in rolling. Bake quickly so as not to dry out or it will not roll.
