Ingredients
- 150 ml Fresh lemon juice (About 3 medium lemons, juiced)
- 100 g Granulated sugar
- 15 g Cornstarch (Maïzena) (About 2 tablespoons)
- 2 Egg yolks (Fresh eggs, preferably pasteurized)
- 200 g Mascarpone (At room temperature)
- 50 g Powdered sugar
- 1 c. à café Vanilla extract (Optional, to round the flavor)
- 200 ml Heavy whipping cream (Cold, at least 30 % fat minimum)
- 4 leaves Fresh mint leaves (For decoration)
Instructions
Prepare the lemon syrup
Juice the lemons to obtain 150 ml of juice. Pour the juice into a saucepan, add the granulated sugar and the cornstarch. Mix with a whisk off the heat until a homogeneous mixture is obtained.
Time: PT5M
Cook the mixture
Place the saucepan over medium‑low heat. Stir constantly with the whisk for about 10 minutes, until the mixture thickens and becomes as smooth as a béchamel.
Time: PT10M
Temperature: Moyen-doux
Incorporate the egg yolks
Remove the saucepan from the heat. Add the two egg yolks in a stream while whisking vigorously to avoid cooking the eggs.
Time: PT2M
Cool the lemon cream
Transfer the preparation to a bowl, cover with plastic film in contact with the surface to prevent a skin from forming. Let cool at room temperature then place in the refrigerator for at least 30 minutes.
Time: PT30M
Whip the cream
In a cold bowl, pour the heavy cream, add the powdered sugar and the vanilla extract. Whisk on medium‑high speed until a firm whipped cream is obtained (about 2 minutes).
Time: PT5M
Mix mascarpone and lemon cream
In a large bowl, incorporate the softened mascarpone. Add the cooled lemon cream and gently mix with a spatula until a homogeneous paste is obtained.
Time: PT3M
Fold in the whipped cream
Add the whipped cream in two batches, lifting the mass with the spatula (folding technique) so as not to deflate it.
Time: PT2M
Plating
Pour the mousse into verrines or small glasses. Smooth the surface with the back of a spoon. Decorate each portion with a mint leaf and, if desired, a lemon zest.
Time: PT5M
Chill
Cover the verrines with plastic film and place in the refrigerator for at least 4 hours (or overnight) before serving.
Time: PT4H
