Mocha Croquembouche
French 40 Mins Prep · 60 Mins Cook
- Preheat the oven to 180°C, gas mark 6. Line a baking tray with parchment paper.
- To make the choux puffs, sift the flour into a bowl. Heat the butter and water until just melted then bring to a rolling boil. Immediately remove from the heat and add all the flour at once. Mix until a smooth dough forms, place back on the heat and cook for approx. 1 minute or until the pastry pulls away from the sides of the pot. Allow to cool until lukewarm.
- Lightly whisk the eggs then beat into the pastry a little at a time until smooth, shiny and of piping consistency.
- Place the pastry in a piping bag fitted with a large plain nozzle. Pipe small blobs of pastry approx. 4cm in diameter onto the baking tray.
- Bake for 25 minutes or until puffed up and golden. Turn off the oven and remove the choux puffs. Using a small paring knife, poke and twist small holes in the bottom of each puff and immediately return to the oven to dry out for 15 minutes.
- To make the mocha custard, roughly chop 150g of chocolate. Separate the egg yolks from the whites. Whisk together the egg yolks and sugar in a large pot set over low heat. Add 450ml of cream and sea salt. Set the pot over medium-high heat and bring the mixture to a boil. Stir continuously until the mixture thickens and coats the back of a wooden spoon, approx. 5-8 minutes. Remove from the heat. Stir in the coffee, chocolate, vanilla extract and mascarpone. Cover and refrigerate until chilled.
- To assemble, place the custard in a piping bag fitted with a medium straight nozzle. Fill the choux puffs with the mocha custard.
- Chop 100g of chocolate. Heat 300g of cream in a small pot until barely simmering. Remove from the heat and add the chocolate. Stir until smooth and keep warm.
- Dip the tops of each puff in the chocolate sauce before stacking them on a serving plate.
