A tantalizing way to make the most of seasonal strawberries.
Purée strawberries, 1/4 teaspoon sugar substitute and jam.
Place milk, egg white, vanilla and 1/2 teaspoon sugar substitute into a food processor or mixmaster and process until thick and fluffy.
Pour mixture into a freezer proof bowl and freeze until beginning to set around the edge.
Remove from freezer and beat until smooth. Swirl through 2/3 of strawberry purée and return to freezer until firm.
Use remaining strawberry purée as a sauce.
