Mix flour and almonds. Cut butter into cubes, add and quickly work into a crumbly dough with your fingertips. Add 2 tablespoons sugar, egg yolk and 1-2 tablespoons cold water. Quickly work into a smooth dough.
Roll out to a rectangle (approx. 15 x 39 cm) on a floured work surface. Grease a tart mould (12 x 36 cm) with lift-off base and dust with flour. Place the dough inside, press the edges firmly.
Cut off any excess dough. Chill the tart for about 30 minutes.
Line the tart with baking paper and fill with dried peas. Bake in a preheated oven (electric cooker: 200 °C/ convection oven: 175 °C/ gas: see manufacturer) for approx. 10 minutes in a blind oven. Remove baking paper and dry peas.
Bake the tart for another 5 minutes. Let it cool down on a cake rack for about 10 minutes. Remove from the tin and let it cool down.
In the meantime, wash the orange hot, grate it dry and finely grate the peel. Halve the orange, squeeze the juice. Bring 3 tablespoons of sugar, cranberries, orange peel and juice to the boil in a saucepan and simmer over a low heat for about 5 minutes.
Remove from the heat and let it cool down. Roughly chop the chocolate and melt it over a warm water bath. Whip the double cream with the whisk of the hand mixer until stiff. Fold into the chocolate. Drain the cranberries and let them drain.
Spread half the cranberries on the tart base. Spread the cream over it and smooth it down. Spread the rest of the cranberries on the cream. Arrange on a cake plate.
