Ingredients
Method
Prepare the Mascarpone Foundation
- Heat the heavy cream in a pan until it reaches a gentle simmer. Stir in the lemon juice.
- Continue to stir over low heat until the cream thickens significantly (it will coat the back of a spoon).
- Let it cool, then pour it into a sieve lined with cheesecloth. Place it in the fridge for at least 8 hours to drain.
The result is thick, spreadable mascarpone cheese.
Bake the Savoiardi Biscuits (ladyfingers)
- Preheat your oven to 180°C (350°F).
- Whisk the egg whites with half the sugar until stiff peaks form.
- In another bowl, whisk yolks with the rest of the sugar and vanilla until pale.
- Gently fold the whites into the yolks. Sift in the flour and cornstarch, folding carefully to keep the air.
- Pipe into 4-inch strips, dust with powdered sugar, and bake for 12–15 minutes until crisp.
Make Cream Filling
- Create a double boiler (bain-marie) by placing a bowl over a pot of simmering water.
- Whisk the 3 egg yolks and sugar for about 5 minutes until thick and pale.
- Remove from heat and let it cool.
- Once cool, fold in your homemade mascarpone and then gently fold in the whipped heavy cream to create a light mousse.
Prepare the Coffee Dip
- Mix the coffee soak ingredients.
Crucial Step: Dip each ladyfinger into the coffee for only 1 second per side. If they soak too long, the Tiramisu will be soggy.
Assemble Tiramisu
- In a rectangular dish, place a layer of soaked ladyfingers.
- Spread half the mascarpone cream over them.
- Repeat with a second layer of biscuits and the remaining cream. Smooth the top with a spatula.
- Generously dust the top with cocoa powder.
- Refrigerate for at least 4 to 6 hours (overnight is highly recommended).
This allows the biscuits to soften into a cake-like texture and the coffee to permeate the cream.
Notes
Why Homemade? Store-bought Mascarpone can sometimes be bland. Making it from scratch with lemon juice gives it a subtle tang that balances the rich coffee and sugar perfectly.
Ladyfinger Tip: Ensure your bowl is grease-free when whisking the egg whites, or they won't reach stiff peaks!
Safety: Cooking the yolks over a double boiler makes this dessert safer to eat while still maintaining the traditional Italian method.
