Remove cheesecake pan from refrigerator. Carefully unmold the cheesecakes from the pan. Using a small spoon, place 1 teaspoon of lemon curd on top of each cheesecake, smoothing to cover evenly. Return to the refrigerator to chill for 30 minutes.
Put the egg whites in the large bowl of the Magimix fitted with the whisk attachment and beat, gradually pouring the sugar mixture through the shoot, until stiff peaks form. Do not over beat. Using a medium spoon, place a dollop of meringue on top of each cheesecake.
Using the back of the spoon, swirl the meringue to form soft peaks. Using a kitchen torch, lightly torch the top of the meringue peaks, browning slightly. Sprinkle with a few strands of lemon zest.
