Make a mixture as for cream cakes; put it into a pastry-bag with a tube of three eighth inch opening. Press the batter onto tins (floured as directed for cream cakes) in strips three and one half inches long, and a little distance apart, the same as lady-fingers. Egg the tops and bake in a slack oven about thirty minutes. Cut open one side and fill with cream filling made the same as for cream cakes. Make a chocolate icing No. 2; dip the eclairs into it, covering them one half. For vanilla or coffee eclairs use fondant icing. Flavor the filling with vanilla or coffee, the same as the icing.
