Ingredients
Method
- Set a heatproof bowl over a pot of barely simmering water (do not let the bowl touch the water). Whisk the egg yolks and sugar constantly 5–8 minutes, until pale, thick, and ribbony — this gently cooks the yolks. Remove and let cool a few minutes.
- Whisk the room-temperature mascarpone and a pinch of salt into the warm yolk mixture until completely smooth.
- In a separate cold bowl, whip the heavy cream to soft-to-medium peaks. Fold it into the mascarpone mixture gently, in two additions, until smooth and stable. Do not overmix.
- Stir the cooled espresso together with the liqueur (if using) in a shallow dish. Dip each ladyfinger quickly — about 1 second per side. Do not soak them; they should be moistened, not saturated.
- Lay a layer of dipped ladyfingers in the bottom of a 9x13-inch dish. Spread half the mascarpone cream over them. Add a second layer of dipped ladyfingers, then the rest of the cream, smoothed flat.
- Cover and refrigerate at least 6 hours, ideally overnight, so it sets and the flavors meld.
- Just before serving, dust the top generously with cocoa powder through a fine sieve.
Notes
The one-second dip is everything — oversoaked ladyfingers turn the whole thing to mush. Cooking the yolks over a double boiler makes the custard food-safe; you can also use pasteurized eggs. Chill overnight so it slices clean, and always dust the cocoa at the very end so it does not absorb into the cream. The perfect finish to an Italian dinner.
