Method
Parmesan Pastry
- Combine the wholemeal flour, plain flour, parmesan and salt in a bowl.
- Using a box grater, grate the cold butter into the flour mixture.
- Add the iced water and use your fingertips to mix until a soft dough forms.
- Shape into a 20cm flat disc, cover with cling wrap and rest for 30 minutes.
- Roll the pastry into a 32cm circle and place onto a perforated round baking tray.
Caramelised Red Onion
- Place the onions, olive oil and salt in a frying pan over medium heat on induction setting 6.
- Cook for 6 minutes, stirring occasionally, or until the onions are tender.
- Add the butter and red wine vinegar and continue cooking for 10 minutes, or until all the liquid has evaporated.
Mozzarella Custard
- Combine all ingredients and set aside until needed.
Ratatouille Tart
- Preheat the oven on Fan Grill at 200°C.
- Combine the capsicum, zucchini, eggplant and red onion with the olive oil, thyme and salt flakes.
- Arrange the vegetables on a universal tray, ensuring the capsicum is skin-side up. Place on shelf level 4 and cook for 12 minutes, or until tender.
- Remove the capsicum skin and transfer all vegetables to a wire rack to drain any excess liquid.
- Change the oven function to Intensive Bake at 170°C and position the rack on shelf level 1.
- Spread the caramelised onion over the pastry, followed by an even layer of mozzarella custard.
- Arrange the roasted vegetables over the custard and top with the sliced mozzarella.
- Crimp the pastry edges to form a protective border.
- Cook on Intensive Bake at 170°C for 35 minutes, or until the pastry base is cooked.
- Change the oven function to Fan Plus at 200°C. Add the cherry tomatoes to the tart and cook for a further 5 minutes.
