How to make cheesecake filling
Mix the strawberry jelly granules with 1 cup of boiling water. Set this aside to cool completely at room temperature, until required.
In a medium size mixing bowl, beat the mascarpone and cream cheese for 3-5 minutes until smooth and fluffy.
Add the condensed milk and vanilla extract to the cream cheese mixture and beat for a further 5 minutes until it is combined.
Add the lemon juice and lemon zest and beat for another 5 minutes.
Pour the filling mixture over the chilled biscuit base and smooth the surface.
Place in the refrigerator to set for at least 30 minutes.
Pour over the cooled strawberry jelly and place back in the refrigerator, allow to chill for 4-6 hours to set completely before serving.
When ready to serve cut the cheesecake into squares and serve with a garnish of fruit or whipped fresh cream.
