Lime Parfait

Directions

1. 1
   Pour about 1-inch (2.5-cm) of water in the bottom of the saucepan and bring to a boil.
2. 2
   Put the zest, lime juice, 1/4 cup (50 mL) of the sugar, egg yolks and salt into a medium-sized heatproof bowl.
3. 3
   Fill a large bowl with ice and a little water to make an ice bath.
4. 4
   Pour 3 tbsp (45 mL) of cold water in a small heatproof custard cup and sprinkle over the gelatine.
5. 5
   Reduce the heat so that the water in the saucepan barely simmers and place the bowl on top.
6. 6
   Using an electric mixer, beat the eggs until the sugar dissolves and the mixture is frothy, light-coloured and warm in the centre, about 3 to 5 minutes.
7. 7
   Turn off the heat and transfer the bowl to the ice bath to cool.
8. 8
   Place the custard cup with the gelatine into the hot water in the saucepan.
9. 9
   Once the gelatine is melted, whisk it into the lime mixture.
10. 10
    Whisk occasionally until the mixture cools.
11. 11
    In a clean bowl with clean beaters, whisk the whites at low speed until frothy, and then add the cream of tartar.
12. 12
    Increase the speed to medium-high, and when the whites turn white and the froth disappears, gradually add the remaining 1/4 cup (50 mL) of sugar.
13. 13
    Continue beating until the whites are thick, resembling thickly whipped cream.In a separate bowl (you can use the same beaters), whisk the cream until soft peaks form.
14. 14
    Whisk a couple of large spoonfuls of the egg whites into the lime mixture to lighten it.
15. 15
    Pour the ice and water out of the ice bath bowl; dry bowl.

    Pour the lightened lime mixture into this cold bowl, then tip the remaining egg whites and the cream mixture on top and fold together gently.

    Pour into a bowl or individual dishes and refrigerate at least 4 hours or until firm.

    Garnish with lime zest and blueberries and serve.
