Step 1

To make strawberry sauce, chop strawberries coarsely. Blend or process strawberries until smooth. Strain purée into a small jug; discard seeds. Stir juice, sugar and enough of the water into purée to make 1 cup of sauce.

Step 2

Beat cream, mascarpone and 1 tablespoon of the sugar in a small bowl with an electric mixer until soft peaks form. Beat egg yolks and remaining sugar in another small bowl with an electric mixer until thick and creamy. Fold egg yolk mixture into mascarpone mixture.

Step 3

Cut biscuits into half or thirds (depending on glasses). Pour 3/4 cup of strawberry sauce into a small bowl; dip biscuits into sauce. Place soaked biscuits into bases of six 3/4-cup (180ml) glasses. Divide the mascarpone mixture into the glasses. Cover and refrigerate for 1 hour. Refrigerate remaining strawberry sauce.

Step 4

Just before serving, pour the remaining strawberry sauce into each glass.
