Leave the mix to sit for at least 12 hours.
Mix and churn between 14°F and 20°F (-6°C and -10°C).

ASSEMBLY AND FINISHING
- Kumquat 120 g
The day before serving:
Make the hazelnut ice cream mix and leave to sit for 24 hours at 40°F (4°C).
Make the Opalys & vanille ganache and leave to set for at least 12 hours in the refrigerator.
Make the kumquat confit and leave to stiffen in the refrigerator.
Make the Opaline powder and store in an airtight box, away from moisture.

On the day of serving:
Make the hazelnut sponge, pour 800g of batter into a half-frame on a baking sheet with a silicon mat.
Bake at 355°F (180°C) for 14/16 minutes.

Once cooled, cut into 6cm circles.
Churn the ice cream mix, then use a piping bag without a nozzle to fill half-sphere molds (Ref: 1489 – H49], smooth, then freeze.
Finish the vanilla Opaline: on a greased silicone mat, sift the powder into a very fine irregular circle shape, about 5/6cm in diameter, and bake at 355°F (180°C) for 2 minutes.
Remove and leave to dry in the oven.

Just before serving:
Wash the kumquats, cut into thin slices and set aside. Beat the ganache in a stand mixer with a whisk attachment, then fill a piping bag with a 20mm plain nozzle.

Plating:
Using a piping bag without a nozzle, spiral 10g kumquat confit onto the plate, place the hazelnut sponge disk on top and press down lightly to create a confit edge around the disk.
Then arrange the half-sphere of hazelnut ice cream on the center of the sponge.
Place a dome of whipped ganache top of the ice cream.
Using a warm spoon, make a small hollow in the center of the dome and fill it with 10g kumquat confit.
Place a few slices of kumquat on the whipped ganache dome.
Finish by carefully placing the vanilla opaline on the dome, pressing down gently to ensure it stays in place.
