1. Begin by making the crumble: rub all the ingredients together and bake at 150°C for 30 minutes. Set aside to cool.
2. Next, prepare the almond crisp: blend the cooled crumble in the food processor, then combine with the melted chocolate and clarified butter. Add the feuilletine. Position a rectangular flan ring on a baking sheet lined with parchment paper or a silicone mat, then pour the mixture into it, spreading to fill the ring.
3. Prepare the cream cheese: dissolve the gelatine in the cream. Combine all the other ingredients, then add the cream/gelatine mix and combine thoroughly. Pour on top of the almond crisp. Bake for 10 minutes at 150°C, then lower the temperature to 110°C and bake for a further 2 hours.
4. Prepare the lemon confit: boil the lemon juice and set aside. Make a dry caramel with the caster sugar and deglaze with the boiled juice. Add the blanched lemon peel and heat for approximately 20 minutes. Strain the now candied peel and set aside, reserving the cooking liquid.
5. Combine the artificial sweetener with the fruit pectin, then add to the reserved cooking liquid and bring to the boil. Add the gelatin and glucose. Blitz the hot candied peel in a food processor, gradually adding the cooking liquid. Pour 150g of the mixture into the flan ring and refrigerate overnight for the flavours to mature. Set aside the remaining lemon confit for a future recipe!
6. Finally, prepare the light yuzu cream: combine the cream, sugar, yuzu powder and mascarpone cheese and bring to the boil. Pour the boiling mixture onto the egg yolks to poach them, and add the gelatine. Gradually pour this mixture over the cocoa butter and white chocolate, stirring thoroughly to make an emulsion. Add the yuzu juice and oil. Stir well, then refrigerate overnight. The following day, whisk and pour into the tart ring on top of the lemon confit. Remove the ring and slice into individual portions measuring 2.5 X 12.5cm.
Garnish as desired.
