Fruit and yogurt get special treatment in this dessert. Fragrant spices and a touch of sugar, along with roasting the peaches, add intense flavour and the spiced, glazed seeds add crunch. Layered with vanilla-perfumed thick and creamy yogurt and you’ve got a parfait fit for company, yet easy enough for every day.
The peaches can be roasted up to 8 hours ahead. Let cool, then cover and store at room temperature until assembling the parfaits. The seeds can be toasted up to 3 days ahead; once cooled, store in a cookie tin at room temperature. The parfaits are best assembled just before serving.
Substitute 3 large black or red plums for the peaches; they may require about 5 minutes longer baking time depending on the firmness of the fruit.
Preheat oven to 400°F (200°C). Line a small baking sheet with parchment paper.
In a small bowl, combine sugar, cinnamon, ginger and allspice.
Place peaches in an 8-inch (20 cm) square glass baking dish; sprinkle with half of the sugar mixture and toss gently to coat. Spread in a single layer. Roast for about 15 to 20 minutes or until peaches are tender and lightly browned. Let cool slightly, or to room temperature.
Meanwhile, in a small skillet, toast sunflower seeds and/or pumpkin seeds over medium heat, stirring constantly, for about 3 minutes or until starting to turn golden; add remaining sugar mixture cook, stirring, for about 2 minutes or until toasted and glazed. Spread out onto parchment paper and let cool.
To assemble, in a bowl, combine yogurt and vanilla. Divide half of the yogurt equally among 6 dessert dishes and top with half of the roasted peaches, then half of the glazed seeds; repeat layers.
