German cherry streusel

1.Preheat oven to 170C. Place cherry juice, sugar and cornflour in a saucepan over medium-high heat and bring to the boil, stirring continuously, then whisk until mixture thickens (2-3 minutes). Stir in cherries, remove from heat, cover tightly with plastic wrap and set aside to cool.

2.For streusel, process ingredients in a food processor until coarse breadcrumbs form. Transfer to a bowl, bring mixture together with fingers to form large lumps about the size of your thumbnail, then set aside.

3.For cinnamon sugar, combine ingredients in a bowl and set aside.

4.For sweet pastry, process flour, butter, sugar and a pinch of salt in a food processor until the mixture resembles coarse breadcrumbs. With the processor running, add egg and vanilla, process until the dough just starts to come together, turn onto a lightly floured surface, knead until smooth and roll out to fit the base of a 20cm x 30cm slice tin lined with baking paper. Top with cherry mixture then streusel and bake until golden (40 minutes). Dust with cinnamon sugar and serve.
