Step-by-Step Instructions
Step 1: Prepare the Lemon Base
Zest the lemons first, then squeeze the juice. Gently heat the lemon juice with sugar until dissolved (do not boil).
Soak gelatin in cold water for 5 minutes, squeeze excess water, then stir into the warm lemon mixture until fully dissolved. Let cool slightly.
🍋 Tip: Cooling prevents the cream from deflating later.
Step 2: Whip the Cream
Whip cold cream to soft peaks. Keep it light and airy, not stiff.
Set aside in the refrigerator.
Step 3: Beat the Egg Whites
In a clean bowl, beat egg whites with a pinch of salt until stiff peaks form.
🥄 This step gives the mousse its cloud-like texture.
Step 4: Combine Gently
Fold the lemon mixture into the whipped cream using gentle movements. Then carefully fold in the egg whites in two additions.
⚠️ Do not overmix—air equals lightness.
Step 5: Chill and Set
Spoon the mousse into serving glasses. Refrigerate for at least 2 hours until set.
