Coarsely chop the couverture and melt it over a hot water bath, let it cool down a little. Separate the eggs. Finely crumble the lady fingers in the universal chopper. Stir the soft fat and sugar with the whisk of the hand mixer for about 5 minutes until very foamy. Gradually stir in the egg yolks.
Stir for another 5 minutes. Add almonds, sponge crumbs and liquid chocolate to the fat-egg mixture. Beat the egg white and 1 pinch of salt until stiff, fold into the dough. Fill the dough into a well greased, flour-dusted saddle of venison form (30 cm long) and smooth it down. Bake the cake in a preheated oven (electric cooker: 200 °C/ convection oven: 175 °C/ gas: level 3) for 40-45 minutes. Leave to rest in the pan for 5 minutes, then turn out onto a cake rack and allow to cool. Heat up the cake glaze and cover the cake evenly. Leave to cool. Chop white chocolate and melt over a hot water bath. Pour into a piping bag and draw strips over the saddle of venison.
