Opale de Rose : Rose Blood Orange Cake

Mix a little of the cold water with the potato starch.
Heat remaining water to 185/195°F (85/90°C).
Pour some more of the water into the water-starch
mixture.
Bring to a boil in your cooking appliance.
Off the heat, add the bloomed gelatin.
Emulsify with a spatula while gradually pouring over the
partially melted chocolate.
Mix as soon as possible with an immersion blender to
perfect the emulsion.
Add the rose water and blend again.
Leave to set for 12 hours in the fridge.

Sprinkle the gelatin over the small amount of pureed
fruit at 40°F (4°C), then wait 15/20 minutes for the
gelatin to bloom.
Heat this mixture to between 120/140°F (50/60°C) to
melt the gelatin.
Next, add the sugar and glucose powder, then pour into
the second part of the purée at 40°F (4°C).
Blend with an immersion blender until smooth and pour
into a mold immediately.

Combine the almond flour, eggs, water and NOROHY rose water.
Beat the egg whites until stiff peaks form, adding all the
sugar at once.
Fold the beaten egg whites into the first mixture, then
fold in the sifted flour

In the bowl of a mixer, combine the blood orange purée
at 40°F (4°C) and the sifted albumin.
Mix and wait 15/20 minutes for the albumin to bloom.
In a saucepan, combine the water and sugar, cook at
245°F (118°C), then add to the purée and albumin once
it appears frothy.
Beat in a stand mixer at medium speed until cool (approx.
85°F or 30°C)

Combine the blood orange purée and the cream, both at
40°F (4°C), then beat in a stand mixer at medium speed
until a frothy texture appears, like a standard whipped
cream.

Sprinkle the gelatin and tara gum into the small amount
of blood orange purée at 40°F (4°C), then wait 15/20
minutes for the mixture to bloom.
Heat it to between 120°F and 140°F (50/60°C) to melt the
gelatin, then add to the second amount of purée at 40°F
(4°C) and blend until smooth.
Combine about one third of the purée with the Italian
meringue, starting to with a whisk to bring the different
textures together.
Add the rest of the purée, using a spatula to combine,
then finish by gently folding in the fruity whipped cream,
to avoid losing as much volume as possible.
Pour into a mold immediately.

Heat the rose water and Absolute Cristal glaze together
until simmering.
Use immediately

The day before:

Make the Opalys Rose ganache and leave to crystallize
at 40°F (4°C) for 12 hours.
Make the gellified coulis, then pour 15g into each halfsphere silicone mold.
Allow to gellify at 40°F (4°C) for approx. 4 hours, then
freeze.
Once frozen, turn out and set aside in the freezer.

The day of serving:

Make the sponge and pour 800g batter into a half-frame.
Bake at 355°F (180°C) for approx. 14/16 minutes.
Once cooled, use a cookie cutter to cut 6cm diameter
disks.
Beat half the Opalys ganache and, using a piping bag
without a tip, pipe 15g of ganache evenly onto each disk
of sponge.
Freeze.
Make the mousse and pour 35g into each 4cm high and
6cm diameter silicone mold.
Put the sponge-ganache insert into place.
Smooth the surface and freeze.

Turn out the cakes and arrange the half-spheres of
gellified coulis in the center.
Make the rose water Absolu Cristal glaze, then spray a
fine layer over the cakes.
Beat the remaining ganache, then using a pastry bag
fitted with a plain 8mm nozzle, pipe a ring around the
half-sphere.
