Plum Hazelnut Crumble Tart

1. Preheat the oven to 180°C/Fan160°C, 350°F, Gas Mark 4.
2. Place the hazelnuts in a small baking tin and roast on the middle shelf of the oven for 5 minutes until pale golden. Cool, then finely chop in a food processor and set aside.
3. Increase the oven temperature to 190°C/170°C Fan, 375°F, Gas Mark 5.
4. Combine the butter, flour, Tate & Lyle Demerara Sugar, baking powder and cinnamon in a food processor and pulse until combined, then add the nuts and milk and whiz again until crumb-like. Using slightly more than half the crumble mixture, line the base and then take it to three-quarters of the way up the sides of the tin, pressing firmly into place.
5. Halve the plums, discard the stones, and cut into smallish pieces. Put the plums in a bowl, add the Tate & Lyle Demerara Sugar, cornflour and lemon juice and mix well. Spoon into the tin and sprinkle over the remaining crumble mixture to cover. Place on the baking sheet and bake on the middle shelf of the oven for 45-50 minutes or until golden brown and bubbling.
6. Leave tart to cool for about 30 minutes before removing from the tin to a plate, dust with Tate & Lyle Icing Sugar and serve.

You will also need a 20cm diameter x 4.5cm deep (8”x1¾”) non-stick fluted tart tin or cake tin with a removable base, lightly buttered.
