½ lb. powdered sugar.
¼ lb. flour.
4 eggs—yolks and whites separate, and beaten very stiff.
1 lemon—all the juice, and half the grated rind.
Drop upon buttered paper, not too near together. Try one, and if it
runs, beat the mixture some minutes longer _hard_, adding a very little
flour. Your oven should be very quick, and the cakes a delicate yellow
brown.
