 1 Place the butter, chocolate, cocoa powder and salt in a bowl on a
 pan of simmering water and melt slowly, stirring occasionally until
 well mixed in.
 2 In a separate bowl, beat the eggs and sugar together until light
 and well creamed, and add the golden syrup and sour cream or creme
 fraiche.
 3 Stir your chocolate mix into this mixture, scraping all the
 chocolate out with a spatula. Once mixed well, pour it into the
 pastry shell. Place into a preheated oven for 40-45 minutes at
 150c/300f/Gas 2. During cooking a beautiful crust will form on top.
 4 Carefully take the tart from the oven and cool on a rack for at
 least 45 minutes – the skin will crack and the filling will shrink
 slightly.
