Over time the ingredients for pound cake changed. Eliza Leslie, who wrote the 1851 edition of Direction for Cookery, used 10 eggs, beat them as lightly as possible, mixed them with a pound of flour, then added the juice of two lemons or three large oranges. This changed the flavor and texture of the cake. In the 2008 issue of "Saveur", James Villas wrote that cake flour would not work in place of all-purpose flour because it lacks the strength to support the heavy batter.
