  • 6 ServingsServings


  • Finely grated zest of 2 lemons
  • 1/2 cup lemon juice
  • 4 eggs, separated*
  • 1 cup plus 2 tablespoons sugar, (9 oz) divided


Set a fine mesh strainer over a medium bowl. Combine the lemon zest, lemon juice, egg yolks and 6 tablespoons (3 oz) sugar in a large microwave safe bowl. Whisk until smooth. Cook in the microwave for one minute. Remove the bowl from the microwave and whisk well. Cook for another minute and whisk again. Cook for 30 seconds and whisk again. Keep cooking in 30 second intervals, whisking between each one, until the curd thickens slightly and coats the back of a spoon. Pour the curd through the strainer into the medium bowl and use a spatula to force as much of the curd through the strainer as possible. Let curd cool to room temperature.

Place the egg whites and the remaining 3/4 cup sugar in bowl of mixer. Place the bowl over a pan of simmering water and stir continuously until the whites are warm and the sugar has dissolved. Using the whisk attachment beat the egg whites until stiff peaks form. Place 1/4 of the egg whites into the bowl with the lemon curd and stir to combine. Gently fold in the remaining egg whites. Pour the mousse into serving cups and chill until cold. (It can also be frozen and eaten like ice cream)

*the egg whites are not cooked in this recipe. If that is a concern use pasteurized egg whites instead and use the leftover unpasteurized ones for a recipe where they are cooked.
