Frozen Tiramisu

Ingredients (serves 8)

• 1 tablespoon instant espresso coffee powder
• 1 cup hot water
• 4 egg yolks
• 1/2 cup caster sugar
• 500g mascarpone cheese
• 2 tablespoons Kahlúa Mocha liqueur
• 10 sponge finger biscuits
• Dark chocolate curls (see tip), to serve

Method

1. Grease a 6.5cm-deep, 12.5cm x 20cm (base) loaf pan. Line base and sides with baking paper, leaving a 5cm overhang at long ends.
2. Combine coffee and hot water in a shallow dish. Stir to dissolve coffee. Set aside to cool.
3. Meanwhile, using an electric mixer, beat egg yolks and sugar for 5 minutes or until pale and creamy. Add mascarpone and liqueur. Beat on low speed until just combined (don’t overmix).
4. Spread one-third mascarpone mixture over base of prepared pan. Dip 5 biscuits, 1 at a time, into coffee mixture, turning to coat. Place, in a single layer, over mascarpone mixture. Repeat layers, finishing with remaining mascarpone mixture. Cover surface with plastic wrap. Cover with foil. Freeze overnight or until firm.
5. Soften at room temperature for 5 minutes before turning out onto a plate. Top with chocolate curls. Serve.
