Preparation
Prepare the Pastry Shell
1| Pulse the Green of London tea in a spice grinder until it becomes a fine powder.
2| Combine the tea powder with softened butter, flour, powdered sugar, brown sugar, almond flour, egg, and honey until a dough forms.
3| Roll out the dough and fit it into your tart pan. Prick the bottom with a fork and refrigerate for 1 hour.
4| Preheat your oven to 320°F (160°C). Bake the crust for about 30 minutes or until the edges are golden brown. Let cool.
Prepare the Citrus Cream
1| Zest 1 bergamot and 2 lemons. Juice all the citrus fruits.
2| In a saucepan, bring the citrus juice, zest, butter, and tea leaves to a boil. Remove from heat and let steep for 15 minutes.
3| In a separate bowl, whisk together the eggs, sugar, and agar-agar.
4| Strain the infused citrus liquid into the egg mixture while whisking constantly.
5| Return the mixture to the saucepan over medium heat. Whisk continuously until it thickens to the consistency of a pastry cream.
6| For a silky finish, blend the warm cream with an immersion blender.
Assembly
1| Pour the citrus cream into the pre-baked tart shell.
2| Refrigerate for at least 2 hours before serving.
