Instructions
Melt the butter
Melt 150 g of unsalted butter in a small saucepan over low heat, then let cool to room temperature.
Time: PT10M
Whisk the eggs and sugar
In the mixer bowl, crack 3 eggs, add 250 g of granulated sugar and whisk on medium speed until the mixture whitens and doubles in volume (7‑8 min).
Time: PT8M
Incorporate the dry ingredients
Sift 150 g of type 45 flour with 3 g of baking powder, add the zest of an untreated lemon, then gently fold into the previous mixture.
Time: PT3M
Add the melted butter
Pour the cooled melted butter into the batter, reduce the mixer speed then increase slightly to homogenize.
Time: PT2M
Spread the batter
Pour the batter onto a 40 × 30 cm sheet lined with parchment paper or a silicone mat. Using a spatula, spread to a layer about 1 cm thick, smooth the edges with your finger.
Time: PT5M
Bake the biscuit
Place the sheet in a preheated oven at 190 °C and bake for 15 minutes, monitoring the color.
Time: PT15M
Temperature: 190°C
Prepare the limoncello syrup
In a small saucepan, combine 60 g of granulated sugar and 60 ml of water, bring to a boil for 5 minutes, then let cool. Add 10 ml of limoncello (or a few drops of vanilla) once the syrup is at room temperature.
Time: PT10M
Soak the biscuit
Brush the baked biscuit with the limoncello syrup using a brush or quickly dip it on a rack, then let cool completely on a rack.
Time: PT5M
Soften the gelatin
Soak 5 gelatin sheets (2 g each) in cold water for 5 minutes.
Time: PT5M
Heat the coconut milk
Heat 300 ml of coconut milk to about 50 °C (thermometer), then add the squeezed gelatin and stir until fully dissolved.
Time: PT5M
Temperature: 50°C
Prepare the whipped cream
Place the mixer bowl, whisk, and liquid cream (250 g) in the refrigerator for at least 30 minutes. Whisk the very cold cream until a firm whipped cream forms.
Time: PT5M
Italian meringue
Whisk 2 egg whites (≈120 g) on medium speed. In a small saucepan, bring 120 g of granulated sugar with 30 ml of water to 121 °C. As soon as the syrup reaches 121 °C, drizzle it onto the whites at about three‑quarters of the volume while continuing to whisk until fully cooled and glossy.
Time: PT10M
Temperature: 121°C
Incorporate the meringue into the whipped cream
Add one third of the Italian meringue to the whipped cream, mix vigorously, then gently fold in the remaining meringue with a spatula to avoid deflating the volume.
Time: PT5M
Mix the gelatinized coconut milk
Pour the warm coconut milk and gelatin mixture into the mousse, first a third while mixing vigorously, then the rest gently to retain aeration.
Time: PT5M
Cut the biscuit into two circles
Using a knife, cut the cooled biscuit into two circles of 22 cm diameter. Remove a band of about 1 cm around the second circle so the biscuit does not overhang the sides of the mold.
Time: PT5M
Assemble the first heart
Place the first biscuit circle on the bottom of the heart mold, brush generously with the limoncello syrup, then pour the coconut mousse up to half the height of the mold.
Time: PT5M
Assemble the second heart
Place the second circle (the one with the band removed) on the mousse, brush again with the syrup, then fill the rest of the mold with the remaining mousse. Smooth perfectly.
Time: PT5M
Initial freezing
Place the filled mold in the freezer for at least 4 hours, ideally overnight, so the mousse solidifies completely.
Time: PT4H
Prepare the small decorative meringues
Whisk 3 egg whites (≈90 g) with 180 g of granulated sugar until stiff peaks form. Add the yellow powder food coloring and mix lightly. Using a piping bag, pipe discs of 2‑3 cm diameter onto a sheet lined with parchment paper.
Time: PT10M
Bake the decorative meringues
Bake the small meringues in a preheated oven at 95 °C for 1 h30. Let cool completely before handling.
Time: PT1H30M
Temperature: 95°C
Unmold and finish
Remove the frozen heart from the mold, place it on a serving plate. Using a kitchen torch, lightly warm the edge to release it easily. Attach the small decorative meringues to the sides of the heart with a bit of coconut mousse. Add three additional small meringues on top for the final touch.
Time: PT10M
