Sous vide foie gras with mushroom duxelle

Begin by preparing the pickled onions. Bring the herbs, sugar and vinegar to the boil in a medium saucepan, then stir in the onions and mix well. Transfer to a sealable container, ensuring the onions are completely submerged, and leave to infuse until ready to serve

To make the jelly, flambé the Amaretto in a saucepan and stir through the water and sugar. Allow to cool slightly, then whisk in the agar agar and bring to the boil. Mix in the gelatine and stir until completely dissolved, then pour into a shallow tray and leave to set in the fridge

Preheat a water bath to 50°C

Place the foie gras into a large vacuum bag and seal. Cook in the water bath for 25 minutes, immediately plunging the bag into iced water once cooked

Meanwhile, place the button mushrooms in a blender and pulse until coarsely chopped. Sweat the shallots and garlic in a saucepan until softened — but not coloured — then add the butter, Madeira, chopped mushrooms, thyme and salt and mix well.

Chop the ceps and add to the pan with a little of their soaking water. Mix well and simmer for 20 minutes until most of the liquid has evaporated, adding the lemon juice to taste. Remove from the heat and set aside, keeping warm until ready to serve

To cook the wild rice, heat a medium sized saucepan of oil until it reaches 200°C. Fry the wild rice for 10 seconds until it puffs up, then remove from the pan and leave to drain on kitchen paper, seasoning with salt

Preheat the oven to 180°C/ gas mark 4

To make the tart, brush the a sheet of pastry with the clarified butter and sprinkle over half the Parmesan, thyme and salt. Brush another pastry sheet and place, butter side down, on top of the other pastry sheet to make a sandwich. Repeat this process with the rest of the ingredients

Use a pastry cutter to cut out 7cm diameter discs and place them carefully onto a lined baking sheet. Bake in the oven for 7 minutes until crisp, leaving to cool on a wire rack

Slice the foie gras into 6 even portions. Heat a nonstick pan over a very high heat and sear the portions quickly on both sides until deep golden brown. Add the butter, thyme and garlic to the pan and baste the foie gras continuously for 10 seconds, then remove from the pan and season generously. Reserve the pan juices

To serve, place the duxelle in a ring on the bottom of the plate, topping with a parmesan crisp. Dice the Amaretto jelly into 1cm cubes and arrange several cubes on top of the crisp along with the foie gras and pickled onions. Garnish with the wild rice, edible flowers and a few dots of pan juices
