Ingredients:
- 9 teaspoons instant espresso powder dissolved in 350ml / 1½ cups water (cooled)
- 250 ml baileys
- 400 grams savoiardi biscuits
- 2 large eggs
- 75 grams caster sugar
- 500 grams mascarpone cheese
- 2 ½ teaspoons cocoa powder
Directions:
- Mix the coffee with 175ml / ¾ cup of the Baileys in a shallow bowl. Dip the biscuits into this liquid; let them soak on each side enough to become damp but not soggy. Line the bottom of a 22cm / 8½ inch square glass dish with a layer of biscuits.
- Separate the eggs, but keep only one of the whites. Whisk the two yolks and the sugar together until thick and a paler yellow, then fold in the remaining 75ml / ¼ cup of Baileys, and the mascarpone to make a moussy mixture.
- Whisk the single egg white until thick and frothy; you can do this by hand with such a little amount. Fold the egg white into the yolky mascarpone, and then spread half of this mixture on top of the layer of biscuits.
- Repeat with another layer of soaked Savoiardi, and then top with the remaining mascarpone mixture.
- Cover the dish with clingfilm and leave in the fridge overnight. When you are ready to serve, push the cocoa powder through a small tea strainer to dust the top of the tiramisu.
