Instructions
Sift the dry ingredients
Mix the flour, baking soda and cocoa powder in a bowl, then sift everything to avoid lumps.
Time: PT5M
Cream the butter and sugar
In a large bowl, beat the softened butter with the granulated sugar until the mixture is pale and fluffy.
Time: PT5M
Incorporate the oil, yolks and vinegar
Add the grape seed oil, egg yolks, white vinegar and red gel food coloring. Mix quickly.
Time: PT4M
Mix the first half of the dry powders with the buttermilk
Pour half of the sifted dry mixture into the batter, add half of the buttermilk and mix until homogeneous.
Time: PT5M
Add the remaining powders and milk
Fold in the rest of the dry mixture and the remaining buttermilk, mixing gently until the batter is smooth.
Time: PT5M
Add the vanilla extract
Pour the teaspoon of liquid vanilla extract and mix lightly.
Time: PT1M
Whisk the egg whites to stiff peaks
In a clean bowl, whisk the egg whites with the mixer until stiff peaks form.
Time: PT5M
Fold in the whipped egg whites
Add the whipped egg whites to the batter in three additions, gently lifting the mixture each time to retain the air.
Time: PT5M
Bake the cake
Pour the batter into the greased half‑sphere mold, bake at 180°C for 30 minutes. Check doneness by inserting a knife blade into the centre; it should come out dry.
Time: PT30M
Temperature: 180°C
Cool the cake
Let the cake cool in the mold for 20 minutes, then unmold onto a rack.
Time: PT20M
Carve the brain shape
With a thin knife, cut a trench in the centre of the cake and round the edges to obtain an OV shape reminiscent of a brain. Keep the crumbs to snack on.
Time: PT10M
Prepare the soaking syrup
Bring 120 ml water to a boil with 100 g sugar for 2 minutes, then let cool completely.
Time: PT5M
Soak the cake
Generously pour the cooled syrup over the cake ensuring it is well absorbed.
Time: PT2M
Prepare the homemade almond paste
In the Cook Expert robot (or any other powerful blender), blend the blanched almonds, egg white and powdered sugar until a smooth paste forms.
Time: PT10M
Form almond paste logs
Divide the paste into several portions, roll between your hands to form logs of varying sizes and wrap them around the cake, leaving a 1 cm gap in the centre to separate the two hemispheres.
Time: PT15M
Brush with “blood”
Mix the liquid honey with the red gel food coloring, then brush the almond paste generously to achieve a bloody effect.
Time: PT5M
