Preheat the oven to 190°C while you pit and slice the nectarines into thin wedges.
6 yellow nectarines
Add the nectarine wedges and whole raspberries to a large mixing bowl. Add the granulated sugar, orange zest and juice, corn flour and ground ginger, and gently mix, making sure all the fruit is covered. Pour the fruit mix out into a 25x25cm baking dish and set aside.
400 g raspberries, 50 g granulated sugar, 1 tablespoon fresh orange juice, Zest from 1 orange, 1 tablespoon corn flour, ½ teaspoon ground ginger
To make the crumble topping, combine the flour, chopped pistachios, light brown sugar, baking powder, cinnamon, ginger and salt. Stir briefly to mix. Add in the cool, room temperature butter, and using your fingertips, or a pastry cutter, rub the butter into the dry ingredients until large crumbs and clumps form.
120 g all-purpose flour, ¼ cup pistachios, 80 g light brown sugar, ½ teaspoon baking powder, ¼ teaspoon cinnamon, ¼ teaspoon ground ginger, ¼ teaspoon salt, 100 g unsalted butter
Scatter the crumble mixture evenly over the prepared fruit and bake for 35 to 40 minutes, until the crumble topping is a deep golden colour and the fruit juices are bubbling up around the edges
Allow to set and cool for 5 to 10 minutes and then serve, with any fruit juices from the bottom of the baking dish and vanilla ice cream.
