7    Eggs, separate out yolks
     3    Egg yolks, additional
 3 1/2 c  Confectioner’s sugar, (1

   3/4 c  Sifted all-purpose flour
     1 tb Lemon juice
   1/8 ts Salt
-FILLING AND ICING-
   1/2 lb (good quality) semisweet or
          -bittersweet chocolate
     1 c  Butter
     1 ts Vanilla extract
     3    Egg yolks *see note
     2 tb Confectioner’s sugar
 To prepare for baking seven layers (the usual number): Tear off seven piece
 of aluminum foil, or baking pan liner paper (NOTE 1), each about 11-inches
 long. Spread softened butter lightly over a 10-inch square area in the
 center of each piece of foil or paper. Sprinkle with flour.
 Shake and tilt the foil or paper to make sure the buttered area is
 thoroughly floured and shake off any excess. On the floured area trace a
 9-inch circle. (Use any 9-inch circular object as a pattern: the bottom of
 a 9-inch springform pan, an inverted 9-inch cake tin, or a 9-inch pot
 cover.) Repeat with remaining pieces of foil or paper. Set aside.
Place rack in the center of the oven and preheat to 450 degrees.
 In the large bowl of an electric mixer at high speed, beat the 10 egg yolks
 for a few minutes til they are pale and lemon-colored. Reduce speed and
 gradually add sugar. Increase speed to high again and and beat for 5
 minutes or until very thick. Reduce speed and gradually add the flour, then
 again increase it to high and beat for 5 minutes more (mixture will be
 almost stiff), scraping the bowl occasionally with a rubber spatula. Mix in
 the lemon juice and remove from the mixer. (The mixture will be very
 thick-use your fingers to get it all off the beaters.)
 Beat the seven whites with the salt until they hold a point- stiff, but not
 dry. Since the yolk mixture is very thick, actually stir a few spoonfuls of
 the whites in to lighten it a bit. Then fold in a few large spoonfuls three
 or four times til the mixture lightens.
Gently fold in the remaining whites.
 With a large serving spoon, place two or three large spoonfuls of the
 batter on one of the pieces of prepared foil or paper. Using the back of
 the spoon, spread the batter thin, slowly rotaing the paper with your left
 hand as you spread the batter with your right hand. Make it thin, but do
 not leave any holes in it. A 1/4- inch thickness should give you seven
 layers. Do not make the edges too thin. Follow the lines closely, but don’t
 worry, the edges can be trimmed later.
 Slide a cookie sheet under the foil or paper and bake for 5 to 7 minutes or
 until the top is golden brown with dark brown spots. If the layers are
 thicker than mine are, they will take longer to bake. If they are not baked
 long enough they will stick to the foil or paper. Repeat with remaining
 layers. If you bake more than one layer at a time, rotate the positions of
 the pans during baking to insure even browning.
 When a layer is baked and out of the oven, lift the corners of the foil or
 paper and invert onto a rack. Peel off the paper and immediately invert the
 layer onto another rack to cool, right side up. (Letting the layer cool
 upside down will make it stick to the rack.) When you run out of racks,
 layers may cool on smooth toweling that has been dusted with confectioner’s
 sugar. When you run out of room, cooled layers may be stacked if you
 sprinkle the tops lightly with confectioner’s sugar and place wax paper
 between them.
 Cooled layers may be trimmed to even the edges. Working on a board, place
 an 8-1/2 inch or 9-inch pot cover or cake pan on the layer. Cut around with
 a small sharp knife and then cut with scissors.
 FILLING AND ICING: Melt the chocolate in the top of a double boiler over
 hot water on moderate heat. Remove from heat, stir until smooth, and set
 aside to cool completely.
 In small bowl of electric mixer cream the butter. Add vanilla and egg yolks
 and beat well. Add sugar and cooled chocolate. Beat until thoroughly mixed,
 scraping the bowl with a rubber spatula.
 Place four strips of wax paper around the outer edges of a cake plate.
 Place one cake layer on the plate and with a long, narrow metal spatula
 spread with a thin layer of the chcolate filling. If you have made more
 than seven layers, the filling must be spread very thin, in order to have
 enough for all. Place another layer on top, adjusting it carefully so that
 the edges are lined up evenly. Continue icing the layers, stacking them as
 evenly as possible.
Spread the remaining chocolate smoothly around the sides first and then
