METHOD

1. To make the pastry, place the flour, icing sugar and butter in a food processor and process until the mixture resembles fine breadcrumbs. While the motor is running, add the egg yolks and iced water and process until the dough just comes together. Turn out onto a clean surface and gently bring together to form a ball. Flatten into a disc, wrap in plastic wrap and refrigerate for 1 hour. 
   
2. Roll the pastry out between 2 sheets of non-stick baking paper to 5mm thick. Preheat oven to 160°C. Line an 18cm (4-cup-capacity) pie tin with the pastry+. Trim the edges and prick the base with a fork. Refrigerate for 15 minutes or until firm. Line the pastry case with non-stick baking paper and fill with uncooked rice or baking weights. Cook for 15–20 minutes, remove the baking paper and rice and cook for a further 20 minutes or until the pastry is light golden. Remove from the oven and set aside.
   
3. To make the filling, place the sugar and 1 cup (250ml) milk in a saucepan over medium heat and bring to the boil. Place the cornflour and remaining milk in a small bowl and stir to combine. Add to the pan and whisk to combine. Add the butter and whisk until melted. Add the lemon juice, rind and egg yolks and cook, whisking continuously, for 3–4 minutes or until thickened. Pour the filling immediately into the pastry case, smooth the top and refrigerate for 1–2 hours or until set.
   
4. To make the meringue, place the sugar, water and cream of tartar in a saucepan over high heat. Bring to the boil, reduce heat to low and cook for 4 minutes. Place the eggwhites in the bowl of an electric mixer and whisk on high speed until soft peaks form. While the motor is running, add the hot sugar syrup in a thin steady stream and whisk for 1–2 minutes or until thick and glossy. Spoon the meringue over the filling and, using a kitchen blowtorch, torch until lightly golden. Serves 6–8.
   

TIPS:

+ When making meringue, it’s important to start with a clean dry bowl and clean tools. Any grease or water can prevent the eggwhites from forming soft peaks. 

+ If the dough is too soft after rolling, place in the fridge for 5–10 minutes or until firm enough to handle. 

+ If you don’t have a kitchen blowtorch, preheat a grill to high and cook for 30 seconds–1 minute or until lightly golden brown.

+ The lemon meringue will keep refrigerated for up to three days.
