Prep: 45 min | Cook: 10 min | Total: 1 hr 10 min

Cost: $5.60 total, $1.40 per serving

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

  1. 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

  2. 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

  3. 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

  4. 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

  5. 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

  6. 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

  7. 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

  8. 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

  9. Chill

    Cover the verrines with plastic film and place in the refrigerator for at least 4 hours (or overnight) before serving.

    Time: PT4H

Critical Success Points

  • Mixing lemon juice, sugar and starch off the heat (prevents lumps).
  • Cooking over medium‑low heat without boiling (preserves texture).
  • Incorporating egg yolks off the heat (prevents curdling).
  • Complete cooling before adding mascarpone (prevents separation).
  • Gentle folding of the whipped cream (maintains aeration).

Safety Warnings

  • The hot mixture can cause burns; handle the saucepan with oven mitts.
  • Use pasteurized eggs or cook the mixture to 75 °C to eliminate any salmonella risk.
