# Instructions:

01 - Set your oven to 170°C to warm up. Melt the butter and set it aside.
02 - Whisk the sugar and egg together until the mix turns pale. Gently add the melted, cooled butter and zest. Whisk again.
03 - Add the clementine juice, olive oil, and milk. Mix in the flour and baking powder next. Pour the batter into a cake mold.
04 - Bake for 30 minutes. Let it cool, then trim to rectangles measuring 28x8cm and 1.5cm thick.
05 - Wrap a round stainless steel insert with cling film. Combine the sugar and pectin in a bowl.
06 - Heat the puree until it simmers. Stir in the sugar and pectin mix, boil for 3 minutes while mixing. Let cool and pour into the insert mold. Freeze it.
07 - Soak the gelatin in water to soften. Warm the milk, heavy cream, and vanilla over the stove. Whisk the egg yolks with sugar in another bowl.
08 - Pour the warm milk onto the egg mix slowly while stirring. Heat to 83°C. Add the gelatin and let the mix cool to about 20°C.
09 - Whip the cream until stiff peaks form. Fold it carefully into the custard base.
10 - Pour the vanilla mousse into a mold. Place the frozen insert in the center, then top with the prepared cake rectangle. Freeze for at least 6 hours.
11 - Remove from the mold and apply a spray coating. Add decorations however you like.

# Notes:

01 - The process takes 3 days: day 1 for cake and insert, day 2 for mousse and assembly, and day 3 for decorating.
02 - For the best results, decorate on a frozen log.
