The CWI Cookbook

 3/4 lb. flour
1 lb. sugar
6 eggs, beaten
1 tsp. rose water

Put three-quarters of a pound of fine flour to a pound of fine sifted sugar; sift both together three times, then add six eggs beaten well, and a spoonful of rose-water; when the oven is nearly hot, bake them, but not too wet.

Comment: Rose-water was a common ingredient in fancy cooking of the 19th century, made by soaking large amounts of rose petals in a small amount of water over a period of days or even weeks. It is most commonly found today in markets catering to fans of Middle Eastern cuisine. If completely unobtainable a possible substitute would be a quarter-teaspoon or so of vanilla or almond extract.
