For the Meyer Lemon Curd:
½ cup (125 ml) lemon juice
1 tablespoon (4gr) lemon zest
1/2 cup (100gr) sugar
3 eggs
2 tablespoon (28gr)butter
In a saucepan set over medium heat, combine the lemon juice, zest and sugar and bring to a simmer. Stir occasionally to make sure the sugar is dissolved. In the meantime, whisk the eggs in a medium bowl just until combined. Once the lemon mixture is hot, slowly pour it over the eggs to temper, continuously whisking to prevent the eggs from scrambling. Return the mixture to the pan set over medium low heat and cook until thick. Do not let it come to a full boil or it might separate. Remove from the heat, stir in the butter and whisk until it is fully melted. Cover the surface with plastic wrap to prevent a skin from forming and let cool to room temperature.
For the chamomille-vanilla bean mousse:
3 egg yolks
pinch of salt
1 1/2 teaspoons powdered gelatin
1/4 cup (25ml) cold water, divided
1/2 cup (100gr)sugar
1/4 cup chamomille leaves, chopped
1/2 vanilla bean, split open and seeded
1 cup (250ml) heavy cream
In the bowl of a stand mixer, whisk the egg yolks and the salt. In a small bowl, sprinkle the gelatin over 2 tablespoons of water, and let it sit while you make the syrup base of the mousse.
Combine the sugar, chamomille leaves and the remaining 2 tablespoons of water in a heavy saucepan. Cover and bring to a rapid boil over medium high heat (prevents crystallization of the sugar on the side of the pan). Once the syrup comes to a boil, uncover and cook until the mixture reaches 238F.
Strain the leaves over a container with a spout, it will be easier to add to the yolks. Pour the syrup slowly and into a steady stream into the egg yolks with the machine running on medium high. Melt the gelatin in the microwave for 10 seconds or until dissolved. Add it to the yolk mixture along with the seeds from the vanilla bean and continue to whisk on medium high until it triples in volume and cools to room temperature.
In a separate bowl, whip the heavy cream to soft peaks. Add it to the mousse base and fold the two gently together. Pour the mousse in a pastry bag fitted with a plain tip (I use Ateco #807).
Layer the Meyer lemon curd and the mousse in jars or ramekins and refrigerate if not eaten right away.
