Gnocchi, Clementine and Chestnut Sea Bass Recipe

Begin by preparing the clementine purée. Add the whole clementines and the split vanilla pod to a large pan and cover with water. Place over a medium heat and bring to the boil, then simmer for about 1 hour until the clementines are completely soft, topping up with extra water if needed

Preheat the oven to 200°C/gas mark 6

Place the potatoes on a baking tray and cook for 1 hour until cooked right through – this could take longer depending on the size of the potatoes

While the potatoes and clementines are cooking, prepare the glaze for the chestnuts and clementines. Add the orange juice, vinegar and thyme to a small pan and place over a medium heat. Allow to cook until reduced by half, then set aside to cool

Once cooked, drain the clementines from the water and place whole in a blender. Blitz to a smooth purée then add the sugar and a pinch of salt and blend again to combine. Pass the purée through a fine sieve and transfer to a piping bag, setting aside until ready to serve

Once the potatoes are completely soft in the middle, remove from the oven and allow to cool slightly. When just cool enough to handle cut in half and scoop out the soft, dry flesh from inside. Pass through a fine sieve so it is completely smooth and weigh out 1kg into a bowl

While still warm add the flour and 1 whole egg to the bowl. Separate the second egg and add the yolk to the bowl, discarding the white. Season with salt and pepper then mix everything together well to form a soft dough. If the mixture feels too wet, add a little more flour to help it bind

Roll the dough into long cylinders and cut into 3cm pieces. Bring a large pan of salted water to the boil and add the dumplings. Cook for a few minutes until they float to the surface, then drain and refresh in iced water. Transfer to an oiled baking tray and set aside until just before serving

Make a brine for the sea bass by stirring the salt into the water until dissolved. Add the fillets and leave for 10 minutes

While the fillets are brining, place the lemon juice and sugar in a pan for the foam and place over a medium heat. Stir until the sugar has dissolved and continue to cook until it forms a syrup. Remove from the heat and transfer into a large bowl, keeping warm until required

Rinse the brine from the sea bass fillets with fresh, cold water and pat dry with kitchen paper

When ready to serve, heat a knob of butter in a pan over a medium heat and add the reserved potato dumplings. Cook in the butter until golden all over and sprinkle over a generous pinch of dried seaweed powder

Meanwhile, add a good drizzle of oil to another pan and place over a medium heat. Lay the sea bass fillets skin-side down in the oil and cook for 5–6 minutes until the skin is golden

Heat the 50g of butter in a third pan over a medium heat and allow to foam. Add the chestnuts and cook for 2–3 minutes, then add the clementine segments and the reserved glaze. Toss everything to warm through and coat in the glaze

Once the sea bass are almost cooked, add a knob of butter to the pan and flip over to cook on the other side for 30 seconds. Add the sea vegetables to the pan so they just wilt in the heat

Finish the lemon foam by adding the stock, cream and lecithin to the warm syrup and frothing the mixture using a hand blender to create a foam

To serve, pipe dots of the clementine purée across each plate and add the sea bass fillets. Divide the dumplings, sea vegetables and glazed chestnuts and clementines between the plates and finish with a dusting of dried seaweed powder and spoonfuls of the lemon foam. Serve immediately
