Asisium:
for the roasted milk and white chocolate mousse:
ingredients:
100 g milk and white chocolate; I went almost exactly halfsies
1 egg yolk
110 g cream
12 g sugar
1/8 tsp gelatin bloomed in 1 teaspoon cream
directions:
Preheat oven to 250 degrees F.
Place chopped chocolate in a baking pan and bake, stirring vigorously with a spatula every 15 minutes, until extremely fragrant, about 40 minutes.
The chocolate will have caramelized; you won’t see much of a color change because there is milk chocolate in addition to the white chocolate, but if you taste it, you will notice a distinctly more complex flavor.
Pour into a bowl; you should have about 85 g of chocolate. If you have more, eat it!
Heat cream, yolk, sugar until 175 d F.
Strain over chocolate.
Allow to sit until chocolate is melted.
Stir in bloomed gelatin and pour into molds.
Freeze until use; place on plate to temper at least 5 minutes before service.

for the nocciola gelato:
ingredients:
1/2 cup milk
1 egg yolk
2 tablespoons sugar
Pinch salt
1/4 cup chopped, toasted hazelnuts
directions:
Heat the milk until simmering. Pour in hazelnuts and steep for at least 2 hours and up to a few days, in the fridge.
Strain and discard the hazelnuts.
Blend all ingredients together with an immersion or regular blender, then pour into a pot and heat gently, stirring constantly, until custard thickens and coats the back of a spoon.
Let cool completely, then spin in an ice cream maker.

for the dark chocolate bonbons:
adapted from Elizabeth LaBau
8 ounces bittersweet chocolate, tempered
1 tablespoon cream
1 teaspoon glucose
1/3 cup passion fruit pulp (find it in the frozen section with other Goya products)
4.5 ounces white chocolate, chopped
directions:
Bring passion fruit purée, glucose, and cream to a boil.  
Place the white chocolate in a heat-safe bowl and pour the cream mixture over.  
Allow to sit for 2 minutes without touching, then stir gently until the ganache is smooth and homogeneous.  
Allow to cool.
Coat your molds with the tempered chocolate, then pipe in a little of the ganache.  
Seal with more chocolate and allow to harden.

for the passion fruit crème:
adapted from Milk Bar
ingredients:
65 g passion fruit puree
35 g sugar
1 egg
1/4 teaspoon gelatin
6 tablespoons butter, cold
1 g kosher salt
directions:
Blend the puree and the sugar and egg together until the sugar granules have dissolved and the mixture is smooth.  
Pour into a pan; clean the blender.
Bloom the gelatin in 1 tablespoon cold water.
Heat the passion fruit curd over low heat, whisking constantly, until it comes to a boil.  
Remove from heat and add it to the cleaned blender.  
Add the gelatin, butter, and salt, and blend until the mixture is “thick, shiny, and super-smooth.”
Allow to cool completely.

for the gianduja:
ingredients:
roughly 1 2/3 cups hazelnuts
scant 1 1/2 cup sugar
2 tablespoons grapeseed oil
big pinch salt
1/3 cup milk powder (or more, to taste)
1/3 cup cocoa powder
2 tablespoons confectioners’ sugar
directions:
Prepare a baking sheet with a silpat.
Bring the sugar to a boil in a dry saucepan, and allow to cook until it reaches a golden-amber color.  
Immediately stir in the hazelnuts, working quickly.
Spread out the brittle onto the silpat as thinly and evenly as possible.
Allow to cool completely, then break into chunks.
Pulverize the praline with the grapeseed oil until liquidy and almost entirely smooth.
Add the rest of the ingredients and mix to combine.
Taste and adjust for your preferences; I wanted this spread to be a deep, dark, chocolate, so I didn’t add much sugar, but I did add a nice big pinch of salt.
Can be stored at room temperature for up to 2 weeks (But it won’t last that long…)

to assemble:
Plate the gianduja first; use a chilled plate.
Pipe a few dots of passion fruit cream around the plate.
Place the bonbons where you would like, then follow with the mousse.
As soon as the mousse is out of the freezer/mold, work quickly, as it will melt.
Next, quenelle a scoop of the gelato and place in the center of the plate.
