    1 dried bay leaf

    40g plain flour

    200ml non-alcoholic white wine

    200ml fish stock

    1/2 cup coarsely chopped flat-leaf parsley

    2 tsp thyme

    2 tsp tarragon

    6 eggs, room temperature

    1 hot-smoked trout, skin and bones removed, flaked

    900g skinless hapuku fillet, or similar white-fleshed fish, cut into 4 cm cubes

    2 tbsp finely grated parmesan

    Olive oil, for drizzling

    Potato crust

    1.8 kg Desiree potatoes, peeled, cut into 5cm pieces

    100ml pouring cream

    200g butter, diced


  • Melt butter in a large saucepan over low heat, add leeks and bay leaf and fry until leeks are very soft and start to caramelise, 20-25 mins.

    Add flour and stir until sandy coloured, 5-7 mins.

    Gradually add non-alcoholic wine, stirring to combine between additions, then add stock in the same way, increase heat to high and bring to the boil, stirring for 1 minute to combine and thicken.

    Season to taste, stir in herbs, then pour into a 2-litre baking dish and set aside.

    For potato crust, boil potatoes in a large saucepan of salted water until tender, 10-12 mins, then drain well, return to pan and add cream.

    Return to heat, bring to the boil, then remove from heat and mash with a potato masher until smooth.

    Gradually add butter, stirring to combine well, season to taste and keep warm over low heat.

    Add eggs to a saucepan of boiling water and cook for 7 mins, then drain, refresh in cold running water, peel, quarter and set aside.

    Preheat oven to 200°C and transfer mashed potato to a heatproof piping bag fitted with a 2cm-3cm plain nozzle.

    Scatter fish and eggs over sauce, scatter with parmesan, then pipe mashed potato over the top to cover.

    Drizzle lightly with olive oil, then bake, turning dish occasionally, until filling is bubbling and the crust is golden, 50-55 mins.

    Serve hot.
