• 300g/10oz white chocolate with hazelnuts
• 6 tbsp milk
• 50g/2oz ratafia biscuits
• 3 tbsp Tia Maria
• 125g/4oz soft unsalted butter
• 3 eggs, separated
• 300ml/1/2 pint lightly whipped double cream
• 150g/6oz dark chocolate
• 300ml/1/2 pint water
• 2 tsp corn flour
• 2 tsp instant coffee
• 1 tbsp Tia Maria
• 1 tbsp double cream

40 minutes preparation

1. Break the white chocolate into a pan, add the milk and heat gently, stirring occasionally, until melted. Pour into a bowl.

2. Meanwhile spread the ratafia biscuits over the base of a dish and sprinkle with the 3 tablespoons of Tia Maria.

3. Beat the butter into the melted chocolate, add the egg yolks then fold in the whipped cream.

4. Whisk the egg whites until stiff then fold them into the chocolate mixture. Finally add the ratafia biscuits. Do not add any left over Tia Maria or the terrine may separate. Pour into a 1kg/2lb loaf tin that has been lined with clear film.

5. Cover and freeze for at least four hours, or overnight.

6. To make the sauce: put the dark chocolate into a pan with all but a tablespoon of the water and heat gently until the chocolate has melted. Stir the cornflour and coffee into the reserved water then add to the pan stirring until smooth and thickened. Add the tablespoon of Tia Maria. Cover the surface of the sauce with clear film to prevent a skin forming and leave to cool.

7. To serve, remove the terrine from the freezer and peel away the cling film. Pour the mocha sauce onto large plates then place a slice of the terrine on top. Place a drop of cream on the sauce and run a cocktail stick through the centre to make a heart.
