Preheat the oven to 375℉ (190℃). Line an 8-inch round pan with wax paper and grease.
Sift together the flour, baking powder, and salt. Set aside.
With an electric mixer, cream the butter and sugar until light and fluffy. Gradually beat in the egg yolks, then add the lemon rind. Fold in the flour mixture in 3 batches, alternating with the milk.
Spoon the batter into the prepared pan. Bake until a cake tester inserted in the center comes out clean, about 35 minutes. Let stand 5 minutes, then unmold and transfer to a rack.
For the covering, sift 4½ cups of the confectioners' sugar into a bowl. Make a well in the center, add 1 egg white, the glucose, and orange food coloring. Stir until a dough forms.
Transfer to a work surface dusted with confectioners' sugar and knead briefly.
Roll out the cake covering to a sheet about ⅛ inch thick.
Gently place the sheet on top of the cooled cake and smooth the sides. Trim the excess and reserve.
From the trimmings cut shapes for the lid. Tint the remaining cake covering trimmings with black food coloring. Roll out thinly and cut shapes for the face.
Brush the undersides with water and arrange the face and lid on the cake.
Place 1 tablespoon of the remaining egg white in a bowl and stir in enough confectioners' sugar to make a thick frosting. Tint with black food coloring, fill a paper piping bag and pipe the outline of the lid.
