01 - Boil 2 cups water and steep Earl Grey tea bags for 5 minutes. Remove tea bags and stir in honey. Let cool to room temperature.
02 - In a heatproof bowl, whisk egg yolks and sugar together over a pot of simmering water for 3-4 minutes until pale and slightly thickened. Remove from heat.
03 - Add mascarpone to the yolk mixture and whisk until smooth and fully combined.
04 - In a separate bowl, whip heavy cream until stiff peaks form. Gently fold whipped cream into mascarpone mixture until fully combined and fluffy.
05 - Quickly dip each ladyfinger into cooled Earl Grey tea and arrange a layer in the bottom of an 8-inch square dish. Spread half the mascarpone cream evenly over ladyfingers.
06 - Add second layer of tea-dipped ladyfingers followed by remaining mascarpone cream. Cover and refrigerate for at least 4 hours, preferably overnight, to set.
07 - Dust generously with cocoa powder and garnish with lemon zest before serving.
