Fold into the yolks and flour. Pour this mixture through a funnel made of white letter paper, press on buttered tins about three inches long, and less than one inch wide, or drop by spoonfuls on buttered tins, sprinkle over powdered sugar, and bake in a slow oven.

Any good cake will do for these, but sponge is preferable. Bake an inch thick in square tins. Cut diamond shape, frost with violet, green and pink and white; flavor with violet, pistachio, rose water and lemon. The effect is very pretty.
