Mascarpone Foam
Mix all ingredients together well in a bowl, adjust seasoning, and pour into a cream whipper (siphon). Charge with 2 gas cartridges and chill.
Granola
Mix all ingredients except the honey and coconut oil in a bowl.
Warm the honey and coconut oil until liquid, then mix in well. Spread everything on a baking tray and roast evenly at about 140 °C for about 40–50 minutes.
Grand Cru Chocolate
Combine the milk, sugar, chocolate, cornstarch, and salt in a pot, bring gently to a boil, and simmer lightly for 1–2 minutes. Transfer to a bowl, cover with plastic wrap directly on the surface (to prevent a skin from forming), and chill immediately in the refrigerator.
After about 2–3 hours the cream should be cold. Gently fold in the whipped cream.
Orange Salad
Peel the oranges with a knife and cut into segments, then marinate with powdered sugar and Grand Marnier.
Assembly
Spoon the granola into the bottom of the glass, layer the chocolate cream on top, then add the orange segments, and finish with the mascarpone foam. For the finishing touch, sprinkle a little more granola, orange zest, and shaved chocolate over the top
