Lemon Meringue Pie
150g (1 cup) plain flour
55g (1/4 cup) caster sugar
75g cold unsalted butter, coarsely chopped
3 lemons, juice and finely grated rind only
3 egg yolks
150g caster sugar
80g unsalted butter
330g caster sugar
1. For Pastry: Blend flour, sugar and a pinch of salt in a food processor until combined, add butter and pulse until mixture resembles coarse breadcrumbs. Add 2 Tbsp iced water and pulse until mixture comes together. Form into a disc, wrap in plastic and refrigerate for 1 hour.
2. Roll pastry onto a floured surface to 5mm thick and use to line a 2cm-deep x 24cm-diameter cake ring placed on a heavy-based oven tray or a shallow 24cm tart tin. Trim and refrigerate for 20 minutes. Preheat oven to 180C. Line pastry with baking paper, fill with pastry weights or rice and bake blind for 15 minutes. Remove paper and rice and bake for a further 5-10 minutes or until golden. Remove and cool to room temperature.
3. For the Lemon Curd: Combine lemon juice and rind in a heatproof bowl placed over a saucepan of simmering water. In a separate bowl, combine cornflour and 2 Tbsp water and stir to combine, then add to lemon mixture and whisk to combine. Add 1 cup boiling water and whisk over simmering water until thick. Remove from heat, whisk in egg yolks, sugar and butter until combined and refrigerate until cold. Spoon mixture into pastry case and smooth surface.
4. For Italian Meringue: Place sugar in a heavy-based saucepan, add 1/4 cup water and stir over low heat until sugar dissolves. Increase heat to high and cook until syrup reaches 115C on a sugar thermometer, then remove from heat. Meanwhile, using an electric mixer, whisk egg whites until soft peaks form, then, with motor running, slowly add hot syrup and whisk for 5 minutes. Reduce speed to low until ready to use.
5. Spoon meringue into a piping bag fitted with a 2cm plain nozzle and pipe 3cm high peaks over lemon filling. Place pie under a hot grill or using a blowtorch, toast meringue until evenly golden.
