This delicious silky, chocolate pie comes from my friend Royal Chef Darren McGrady. Darren not only worked for the Queen but also for Princess Diana and her boys up until her untimely death. He's a wonderfully talented chef and a delightful man. I have a number of his recipes from his fabulous cookbook Eating Royally on Goodtaste.tv...including the recipe for Prince William's groom's cake.
Preheat the oven to 350 degrees and then prepare the pastry case/shell – In a large bowl add the flour and sugar and rub in the butter to resemble fine crumbs. Add the egg yolk and cream and form the paste into a ball.
Roll out the paste and line a 9 inch flan ring, then part bake the flan.
Prepare the filling – Place a mixing bowl over a pan of boiling water (like preparing hollandaise) and add 2 eggs, ½ tsp cinnamon, ½ cup sugar, ½ tsp vinegar and the salt. Whisk until the mixture starts to foam and then remove the bowl from the top of the pan to a cool surface. Continue whisking until the mixture reaches the ribbon stage. Pour onto the base of the flan and return to the oven until the filling has risen and is firm to the touch – about 15 minutes. Remove from the oven to a cooling rack and allow the filling to sink back into the shell. This is the first layer of the flan.
Melt the 6 ounces of chocolate and add the water and egg yolks. Whisk until combined. Spoon half of the chocolate mix over the top of the sunken filling and return the flan to the oven for a further 5 minutes. Remove from the oven and allow the flan to cool completely. This is the second layer of the flan.
Beat the cream and cinnamon until stiff and carefully spread half of the mix into the flan. This is the third layer.
Fold the remaining cream and cinnamon mix into the remaining chocolate mix and spread into the flan. This is the fourth layer. Sprinkle on the grated white chocolate and refrigerate until set. – About 1 hour.
