01 - Boil 2 cups water and steep Earl Grey tea bags for 5 minutes. Remove bags and stir in honey. Allow to cool completely to room temperature.
02 - Whisk egg yolks and sugar in a heatproof bowl set over a pot of simmering water, creating a double boiler. Whisk continuously for 3-4 minutes until mixture becomes pale and slightly thickened. Remove from heat immediately.
03 - Add cold mascarpone cheese to the warm yolk mixture. Whisk vigorously until completely smooth and no lumps remain. Set aside.
04 - In a separate chilled bowl, whip heavy cream using electric beaters until stiff peaks form. The cream should hold its shape when beaters are lifted.
05 - Gently fold one-third of whipped cream into mascarpone base to lighten. Fold in remaining cream until fully incorporated and mixture is fluffy and airy.
06 - Working quickly, dip each ladyfinger briefly into cooled Earl Grey tea—do not soak, just 1-2 seconds per side. Arrange dipped biscuits in a single layer in bottom of 8x8 inch dish.
07 - Spread half of mascarpone cream evenly over ladyfingers using an offset spatula, ensuring complete coverage to edges.
08 - Repeat dipping process with remaining ladyfingers and create second layer over cream. Top with remaining mascarpone mixture, spreading smoothly.
09 - Cover dish tightly with plastic wrap and refrigerate for minimum 4 hours, preferably overnight, to allow flavors to meld and texture to firm.
10 - Just before serving, dust surface generously with cocoa powder using a fine sieve. Garnish with fresh lemon zest if desired. Slice and serve chilled.
