What’s the serving size?

Serves 8

What do I need?

For the Pistachio Mousse

½ cup pistachio paste
Or if you prefer to make your own you will need:
1 cup unsalted pistachios, shelled
2 tbsp caster sugar
½ tsp vanilla extract
2 -3 tbsp milk, just enough to blend

For the Mascarpone Cream

1 cup thickened cream, chilled
½ cup icing sugar
500 g mascarpone
1 tsp vanilla extract

For the Tiramisu

1 ½ cups strong espresso, cooled
2-3 tbsp coffee liqueur or Marsala
250 g savoiardi biscuits

For the Chocolate Ganache

150 g dark chocolate, finely chopped
½ cup cream
2 tbsp unsalted butter

To Garnish

¼ cup chopped pistachios

How do I make it?

If making your own pistachio paste begin by adding pistachios, sugar and vanilla to a food processor and blitzing until fine. Add milk, a little at a time until it forms a thick, smooth paste. Set aside.
Make the mascarpone filling by beating cream and icing sugar together until soft peaks form. Add mascarpone and vanilla and beat until silky and smooth. Divide the mixture in half. Stir pistachio paste into one half to create the pistachio mousse layer.
Mix espresso and liqueur in a shallow dish.
Quickly dip each biscuit and place in a single layer in a square or rectangular dish.
Spread the pistachio mousse over the biscuits, then add another layer of dipped biscuits. Spread the plain mascarpone mixture over the top and smooth the surface.
Prepare the chocolate ganache by heating cream until steaming. Pour cream over the chocolate and allow to sit for 1 minute, then add butter and whisk until glossy. Cool slightly, then pour over the tiramisu.
Refrigerate tiramisu for at least 4 hours, preferably overnight, to set.
Sprinkle with chopped pistachios before serving.
