Tiramisu with Grand Jasmin Chun Feng Tea

Preparation

• Steep 10 g of tea in 100 mL of water at 75°C (165°F) for 3 minutes. You will use the brewed tea to make a syrup.
• In a small saucepan, warm 150 g (5 oz) of mascarpone over low heat.
• Add 2 Tbsp water to thin the mascarpone and prepare the mixture for steeping.
• Once the mascarpone has melted and reached a temperature of 75°C (165°F), remove from heat and steep 25 g of tea in the liquid for 5 minutes, covered.
• Remove the tea bag or leaves, then refrigerate the infused mascarpone for approximately 30 minutes to thicken. Mix into the remaining mascarpone.
• Prepare the syrup: pour the brewed tea and powdered sugar into a small saucepan.
• Bring to the boil for 5 minutes, then remove from heat. Transfer to a bowl and let cool.
• Put the gelatine in a large bowl of cold water for 10 minutes to soften.
• Separate the eggs.
• Beat the egg whites until they turn opaque and start to become frothy. Gradually add half the caster sugar, continuing to beat until the mixture holds stiff peaks.
• Beat the yolks with the remaining caster sugar for 5 minutes or until they double in volume. The mixture will become pale yellow and frothy.
• Add the mascarpone to the egg yolk/sugar mixture in three parts, then whisk to obtain a smooth texture.
• Gently wring out the gelatine sheets, then place them in a small bowl and melt for a few seconds in the microwave. Add the crème fraiche, stirring vigorously.
• While whisking quickly, add the crème fraiche mixture to the mascarpone/egg white mixture. It is very important to work quickly so that the gelatine does not set.
• Next, delicately fold in the egg whites, taking care not to deflate the mixture.
• Dip the biscuits quickly in the syrup and arrange them in your dish or in the mousse ring (set on a cutting board or plate covered with clingfilm for easy removal).
• Do not leave the biscuits in the syrup for too long or the excess will seep into the tiramisu.
• Assembly: Cover the biscuits with a layer of mascarpone mixture, then add another layer of syrup-dipped biscuits, and finally cover with the remaining mascarpone mixture.
• Smooth the surface, cover with clingfilm, and refrigerate overnight before serving.
