Walnut and salted caramel pie

Pastry for a case can be grated rather than rolled out. Chill the dough and, once firm, grate it evenly over the base of the pie dish and press quickly to join it together. This reduces the risk of overworking the gluten and it’s easier, too. Ensure the pastry is pressed into the dish evenly so it cooks uniformly.

    120g butter, chilled, coarsely chopped

    3 egg yolks

    Salted caramel

    200g caster sugar

    100ml pouring cream

    80g butter, coarsely chopped


Method

  • For sweet pastry, process flour, icing sugar and 1 tsp salt in a food processor to combine, then add butter and process until fine crumbs form, then add yolks and process to combine.

    Tip mixture out onto a work surface and bring together with the heel of your hand.

    Wrap in plastic wrap and refrigerate for 1 hour to rest.

    Meanwhile, preheat oven to 150°C.

    Roast walnuts on an oven tray until golden, 10-15 mins.

    Cool briefly, then process in a food processor until coarsely chopped. Set aside.

    Coarsely grate pastry evenly over base of a 25cm-diameter pie dish, then press evenly onto base and up sides. Pinch rim to create a crimped effect.

    Refrigerate pastry case for 1 hour to rest.

    For salted caramel, stir sugar and 80ml water in a saucepan over medium-high heat, brushing crystals down sides of pan, until sugar dissolves, then bring to the boil and cook without stirring until dark caramel, 6-8 mins.

    Remove from heat and stir in cream, butter, 100ml water and 1½ tsp salt (be careful, caramel will spit).

    Return to heat and stir until smooth, 1-1½ mins.

    Stand to cool briefly, 15 mins.

    Preheat oven to 170°C.

    Whisk eggs and yolks together in a bowl, then whisk in caramel, flour, apple juice, vanilla seeds and a pinch of salt.

    Stir in chopped walnuts, then pour into pastry case and bake until set and golden, 25-35 mins.

    Dust with icing sugar and serve with cream or ice-cream.
