Lord Mayor's trifle

For the trifle, start with the chocolate jelly by breaking up the dark chocolate and place into a large mixing bowl

In a saucepan, bring the milk and water to the boil. Squeeze the excess water from the gelatine and whisk it in along with the cocoa, then pour through a fine sieve over the dark chocolate

Leave the mixture to sit for 2 minutes to allow the chocolate to melt, then whisk together well. Pour into a square/rectangle plastic container and place in the fridge to set

For the coconut sponge, toast the desiccated coconut. Preheat the oven to 150ºC/gas mark 2. Spread the desiccated coconut thinly and evenly across a baking tray. Bake the coconut for 20 minutes, stirring every 5 minutes to ensure coconut browns evenly. Set aside to cool

In a bowl, whisk the egg whites, slowing adding 40g of the sugar in a mixing bowl until soft peaks form. In another bowl, cream the remaining 105g of sugar and egg yolks and then fold into the meringue

Gently fold the plain flour, corn flour and the toasted coconut into the batter. Spread the coconut batter onto a baking tray lined with greased parchment paper and bake at 200ºC/gas mark 6 for 4-5 minutes. Set aside to cool

To make the cream, whisk together the créme fraîche and double cream until stiff before placing in a piping bag and into the refrigerator

To start the vanilla custard, heat the milk, double cream and vanilla pod in a pan and bring to the boil and remove from the heat

Meanwhile, whisk together the yolks and sugar untile pale. Slowly, pour the hot cream mixture onto the yolks, while whisking. Add this mixture back into pan, and cook out over a low heat until it reaches 80˚C or is thick enough to coat the back of a spoon

Squeeze the excess water out of the gelatine before adding to the mixture and stir until dissolved. Once the gelatine has dissolved, strain the mixture, cover and chill to set. When the custard has set, beat and put into a piping bag

To serve the trifle, cut the coconut sponge and chocolate jelly and and place at the base of your chosen trifle glass. Generously pipe over the custard and then finish by decorating with small dollops of the piped whipped cream
