Muscadel granita

1 Preheat the oven to 180°C.
2 Place the butternut slices on a baking tray and drizzle with the olive oil. Season to taste. Roast in the oven for about 10 minutes, or until soft on the inside and crisp on the outside.
3 Meanwhile, heat the sunflower oil in a saucepan over a high heat and deep-fry the sage leaves for a few seconds, or until crisp and vibrant green in colour. Drain on kitchen paper.
4 Arrange the butternut slices on a platter and scatter over the fried sage leaves and crumbled feta. Drizzle with the raspberry vinaigrette and serve immediately.
5 To make the vinaigrette, combine the sugar, water and raspberries in a saucepan over a low heat. Cook gently until the raspberries have softened, then set aside to cool. Once cool, whisk in the vinegar.
