Nigella Lawson's chocolate key lime pie

It's extraordinary how potent cheap confectionery is. Proust may have had his madeleines, but my taste memories are shamelessly low-rent; I am forever, it seems, trying to recreate the so-long-ago-savoured delights of the sweetie jar. This is yet another evocation of the chocolate limes of my childhood. Luckily, it tastes how I impossibly remember them, not as they would really be, were I to eat one now. My version of this classic American pie doesn't have the traditional meringue topping, nor, of course, does it require Florida key limes - limey limes do it for me.Serves 6-8
digestive biscuits 300g
cocoa powder 1 x 15ml tbsp
soft unsalted butter 50g
dark chocolate chips 50g
sweetened condensed milk, preferably chilled 1 x 397g can
limes 4, to give approx. 2 x 15ml tablespoons finely grated zest and 175ml juice
double cream 300ml
best-quality dark chocolate 1 squareYou will also need:
1 x 23cm x 5cm deep fluted tart tin with loose basePut the biscuits, cocoa powder, butter and chocolate chips into a food processor and process to a dark, damp, sandy consistency. Tip into a fluted tart tin, and press onto the base and up the sides. Place in the fridge to chill while you make the filling.Pour the condensed milk into a bowl. Zest the limes into another bowl and reserve for decoration later. add the juice of the limes to the condensed milk, whisking to mix.Pour in the double cream and whisk together - in a freestanding electric mixer or with a hand-held one - until thick, then spoon the mixture into the chilled biscuit crust and use the back of the spoon to finish off the top in a swirly fashion, leaving the soft filling encircled by dark crust.Chill the pie in the fridge for 4 hours (if the condensed milk was chilled), until firm, or, ideally, covered overnight.when you are ready to serve, unmould the pie from the tart tin, but leave it on the base.Grate the chocolate to give a light dusting to the top of the pie and then sprinkle with the lime zest. This is important because without food colouring the pie will seem too pallid to conjure up the limes that flavour it. Serve immediately, as it will become soft if kept out of the fridge for too long.The pie can be made 1 day in advance. When chilled and firm, tent with foil (try not to touch surface of pie with foil as it will leave marks) and store in fridge. Store the zest in a bowl, tightly covered with clingfilm. Decorate with zest just before serving. The pie will keep for a total of 2-3 days in the fridge.

Cover the pastry bases with a ring of baking paper, place baking beans (or rice) on top and bake in the oven for 15 minutes. Remove from the oven. The pastry should feel slightly dry to the touch and be golden brown in colour. Cool.To make the custard, mix the sugar and egg yolks together in a heat-proof bowl. Add flour and cornflour and mix well. In a saucepan, bring the coconut milk to a gentle boil. Once boiling, remove from the heat and pour slowly into the egg and sugar mixture, stirring continuously. Mix well and pour back into the saucepan. Heat again until boiling and continue to stir for another minute or so until it thickens. Remove from the heat and cool. Put to one side until you are ready to assemble the tarts.To assemble the tarts, spread the cooled coconut cream into each of the pastry cases. Peel and slice the mango and place on top of the custard. Garnish with edible flowers and serve with the ginger ice cream on a bed of desiccated coconut.
