Instructions

Coffee soak25 mins

1Brew and sweeten5 mins
  • Brew
    Strong espresso or moka coffee
    400 ml
    medium-dark or Italian roast arabica, not filter or instant
    strong and pour it into a wide shallow bowl.
  • Stir in
    Caster sugar
    15 g
    just enough to round the bitterness
    while it is still hot.
2Cool, then add the rum20 mins
  • Leave the coffee to cool completely, which takes about 20 minutes in a wide bowl.
  • Stir in
    Dark rum
    40 ml
    or cognac
    once it has dropped below 40°C (fan 20°C).

Crema28 mins

1Cook the zabaglione10 mins
  • Set a heatproof bowl over a pan holding 3 cm of barely simmering water, making sure the bowl does not touch the water.
  • Whisk
    Egg yolks
    6 large
    about 110 g
    ,
    Caster sugar
    130 g
    drop to 110 g for a less sweet crema
    ,
    Fine sea salt
    ¼ tsp
    and
    Dry Marsala
    60 ml
    Marsala Superiore secco, not sweet Marsala
    together in the bowl and keep whisking without stopping.
  • Cook until the mixture has roughly tripled and reads 80°C (fan 60°C) on a probe thermometer, which takes 8 to 10 minutes.
  • Take it off the heat as soon as it falls from the whisk in a ribbon that sits on the surface for a beat.
2Whip it cold8 mins
  • Scrape the zabaglione into a stand mixer and whip on medium-high for 5 to 8 minutes.
  • Stop when it is pale, mousse-thick and no longer warm against the back of your hand, around 25°C (fan 5°C).
3Fold in the mascarpone5 mins
  • Beat
    Mascarpone
    fridge-cold, with any whey poured off, 500 g
    minimum 45% fat
    on the lowest speed for 30 to 45 seconds, just until smooth.
  • Slacken it with a third of the cooled zabaglione, still on the lowest speed.
  • Fold in the rest by hand in two additions, cutting down through the middle and lifting from the bottom.
4Fold in the cream5 mins
  • Whip
    Cold double cream
    150 ml
    35% fat or higher
    to soft peaks, the point at which it slumps as the whisk lifts.
  • Fold it into the mascarpone base in two additions and stop as soon as it is homogeneous.

Savoiardi & Dusting24 hrs 35 mins

1Build the layers15 mins
  • Smear two tablespoons of crema across the base of a 20 cm by 25 cm dish.
  • Divide the cooled coffee between two shallow bowls, so the second layer is not dipped into biscuit crumbs.
  • Dip half the
    Savoiardi
    290 g
    about 28 to 30 dry Italian ladyfingers, not soft sponge fingers
    flat for one second a side and lay them in the dish, breaking pieces to fill the edges.
  • Spread over half the crema, about 1½ cm deep, and sift a light dusting of
    Dutch-process cocoa
    15 g
    dutched rather than natural, so it does not fight the coffee
    across it with
    Finely grated 70% dark chocolate
    30 g
    Optional · between the layers, for texture
    .
  • Dip and lay the remaining savoiardi at ninety degrees to the first layer, cover with the rest of the crema and smooth it flat.
2Chill overnight24 hrs
  • Cover the dish and refrigerate for a full 24 hours.
  • Leave the top bare for now, because cocoa dusted this early draws moisture out of the crema and goes blotchy.
3Dust and serve20 mins
  • Take the tiramisù out of the fridge 20 minutes before serving, so the fat softens and the aromas open.
  • Sift the remaining cocoa over the top just before it goes to the table.
  • Cut with a hot dry knife, wiping the blade between slices.

Tips & Notes

  • Why 80 C: Sugar and Marsala push the yolks' curdling point from about 65 C to past 85 C, so the eggs pasteurise fully without scrambling. If you would rather not sail that close, hold them at 72°C (fan 52°C) for a full minute instead.
  • Split mascarpone: Warm mascarpone, over-beating, or a zabaglione that went in still hot will all break the crema into grains. Caught at the first fine grain, a tablespoon of cold cream whisked in by hand can sometimes pull it back.
  • One second a side: Savoiardi are capillary sponges and hold far more than they need, so the puddle under the dish is almost always over-dipping. Warm coffee does the same damage faster, which is why the soak must be completely cold.
  • Without alcohol: Replace the Marsala with 60 ml of strong coffee and leave the rum out of the soak. You lose aromatic reach, not structure.
  • Make ahead: It keeps three days covered in the fridge, softening a little each day, and freezes well. Thaw overnight in the fridge and dust at the table.
