Instructions
Soften the butter
Melt the butter into a paste in the microwave on low power, in 10‑second intervals, stirring between each interval until a creamy consistency is achieved.
Time: PT2M
Prepare the orange sponge
In the mixer bowl, incorporate the softened butter and granulated sugar, then beat until a pale mixture forms. Add the eggs one by one, beating for a few minutes. Fold in the orange zest and orange juice, mix. Sift the flour and baking powder, gently fold them in using a spatula.
Time: PT7M
Bake the sponge
Spread the batter on a baking sheet lined with parchment paper using a palette, forming a rectangle 31 cm long. Bake in a pre‑heated oven at 180 °C for 18 minutes, watching the colour.
Time: PT18M
Temperature: 180°C
Prepare the orange cremeux
Soften the gelatin sheets in cold water (5 min). In a saucepan, bring the orange juice to a boil. In a bowl, whisk the eggs with the granulated sugar and orange zest. Pour the boiling orange juice over the egg mixture while whisking, then return everything to the saucepan. Cook over low heat, stirring until boiling, then let boil for 1 minute. Remove from heat, stir in the drained gelatin, then add the softened butter. Mix until smooth.
Time: PT10M
Freeze the cremeux
Pour the cremeux into the silicone insert and place in the freezer until fully set (about 2 hours).
Time: PT2H
Prepare the orange‑honey syrup
In a small saucepan, combine orange juice, granulated sugar and honey. Bring to a boil, then let cool completely before adding the Cointreau.
Time: PT10M
Whip the cream
In a very cold bowl, whisk the well‑chilled cream until firm peaks form. Keep refrigerated.
Time: PT5M
Prepare the sugar syrup for the mousse
In a small saucepan, bring the sugar and one‑third water to a boil, then cook for 2 minutes over medium heat.
Time: PT5M
Mix eggs and syrup
Break the eggs into a clean mixer bowl, whisk lightly, then slowly pour the hot syrup in a stream along the side of the bowl. Continue beating until completely cooled; the mixture should turn pale.
Time: PT7M
Melt chocolate and butter
Melt the dark chocolate with the butter in a bain‑marie or microwave on low power, stirring until a smooth, warm mixture is achieved.
Time: PT5M
Incorporate cocoa and eggs
Add cocoa powder to the melted chocolate, mix, then vigorously fold in half of the egg‑sugar mixture, followed by the rest gently.
Time: PT4M
Mix the chocolate mousse
Gently fold the whipped cream into the chocolate mixture to preserve volume, then add the diced candied orange peel.
Time: PT4M
Assembly – first layer
In the log mold, spread half of the chocolate mousse. Arrange the diced candied orange peel on this layer.
Time: PT3M
Insert the orange cremeux
Place the completely frozen silicone insert in the centre of the mousse, pressing lightly.
Time: PT2M
Complete with chocolate mousse
Cover the insert with the remaining chocolate mousse using a palette, leaving space for the sponge.
Time: PT3M
Prepare the sponge band
Cut an orange sponge strip to the dimensions of the mold (about 31 cm × 4 cm). Place it on the chocolate mousse, press lightly, then soak with orange‑honey syrup.
Time: PT5M
Freeze the assembled log
Place the complete log in the freezer until fully set (about 2 hours).
Time: PT2H
Unmoulding
Quickly run the kitchen torch along the mold edge to lightly warm the border, then unmould the frozen insert. Return the log to the freezer while waiting for the glaze.
Time: PT3M
Prepare the chocolate glaze
Soften the gelatin in cold water. In a saucepan, bring glucose, sugar, water and cream to a boil. Remove from heat, add the drained gelatin, then cocoa powder. Pass the mixture through a fine sieve and let cool to 35 °C.
Time: PT10M
Temperature: 35°C
Glaze the log
