This Pistachio Tiramisu is the no-bake dessert recipe you have been waiting for! Layers of boozy coffee-soaked ladyfinger biscuits layered with pistachio mascarpone cream and dusted with cocoa powder.
Place the pistachios in a frying pan and lightly toast them. Then divide the pistachios in half, add half of the nuts to a food processor and blend until fine. Roughly chop the remaining nuts. Set aside.
Place the egg yolks and sugar into a bowl of a double boiler set over simmering water. Whisk the eggs and sugar over medium heat until light in color and creamy. The mixture must be at the ribbon stage, it is ready when it holds a figure 8 for a few seconds.
Add the mascarpone to the egg yolk mixture and gently mix the two together with a rubber spatula and then a hand whisk to make sure there are no lumps.
Add the cream and vanilla extract to a bowl of an electric mixer fitted with a whisk attachment, and beat at a low speed until stiff peaks form. This can take up to 10 minutes.
Gently fold the whipped cream into the egg and mascarpone mixture using a rubber spatula.
Add the finely blended pistachios to the cream mixture and fold to combine.
Pour the coffee and alcohol into a shallow dish, soak the finger biscuits one at a time in the liquid, and lay them into your serving dish - creating a layer of soaked biscuits. Then pour half of the mascarpone mixture over the biscuit layer and smooth it out with a spatula. Place the second layer of soaked biscuits onto the cream and then top this with the remaining mascarpone mixture. Place the dish in the fridge for about 6 hours or overnight to set.
Remove the set tiramisu from the fridge and dust it with cocoa powder then use a fine grater to grate the chocolate over the top, sprinkle the remaining crushed pistachios over the top of the dessert, and serve cold. Enjoy!
