Preparation

• The day before or at least 6 hours in advance, start by making the coconut mousse: Whip the heavy cream with mascarpone in a very cold bowl, adding the powdered sugar gradually. Chill in the refrigerator while you prepare the rest.
• Soak the gelatin sheets in a large bowl of cold water.
• Heat the coconut milk in a saucepan, and when it’s warm, remove from heat and add the squeezed gelatin.
• Let it cool a bit, then gently fold it into the previously made whipped cream using a spatula.
• Pour the mousse into hemisphere molds, adding a teaspoon of spread halfway, cover it, then smooth it with a spatula.
• Place it in the freezer for at least 6 hours.
• Make the Breton shortbreads: Mix all the ingredients until you get a dough.
• Let it rest in the refrigerator for 30 minutes.
• On a floured surface, roll out the dough to about an inch in height.
• Cut out circles, then bake for 10 minutes at 180 degrees. Use rings to maintain a round shape (grease and flour them, or use tartlet molds).
• Let them cool completely.
• Remove the domes from the molds and place them on the cocoa shortbreads.
• Let them thaw for 2 hours at room temperature, then sprinkle grated coconut over the entire dome.
• Tip: If you want the spread to be gooey, enjoy it at room temperature. Bon appétit!
