1

Preheat a water bath to 80°C

To begin, place the onions in a vacuum bag with the olive oil, salt and sugar. Seal in a chamber sealer and place in the water bath for 4 hours. Set the onions aside and increase the temperature of the water bath to 90°C

5g of sugar
20 baby onions, peeled
50ml of olive oil
5g of salt

3

Place the bacon in a vacuum bag and seal in a chamber sealer. Cook in the water bath for 1 hour, then plunge into iced water to refresh. Remove the bacon from the bag and cut into 5mm dice

200g of smoked streaky bacon

4

Preheat the oven to 190°C/gas mark 5

5

Bake the potatoes for 1 hour, or until tender and cooked through. Whilst still warm, cut the potatoes in half, scoop out the flesh and pass through a fine drum sieve

4 large Maris piper potatoes

6

Weigh out 150g of the dry mashed potato and place in a mixing bowl with the remaining gnocchi ingredients. Mix until fully combined, then transfer to a piping bag. Cut the piping bag 5cm from the tip

1 pinch of curly parsley
50g of potato flour
50g of egg
20g of egg yolk
2g of salt
1 pinch of dill, chopped

7

Preheat a water bath to 80°C

Line a work surface with a layer of cling film. Pipe the gnocchi onto the cling film in a long, continuous ‘sausage’, approximately 40cm in length. Roll the cling film around the gnocchi and tie each end. Repeat this process with the remaining gnocchi mix

9

Poach the gnocchi in a water bath for 10 minutes. Refresh in iced water, then remove the cling film and cut into 2.5cm long pieces. Set aside in the refrigerator until required

10

For the horseradish cream sauce, heat the oil in saucepan over a high heat. Add the reserved sea bass bones and roast until all of the moisture has evaporated. Add the vegetables and continue to cook until the vegetables have slightly softened

3 garlic cloves, chopped
50ml of vegetable oil
1 onion, roughly chopped
1 leek, roughly chopped

11

Deglaze the pan with the white wine and reduce by half. Add the cream, bring to the boil and once boiling point is reached, reduce the heat to low and simmer gently for 15 minutes. Add the grated horseradish, then pass the finished sauce through a fine sieve

400ml of whipping cream
400ml of white wine
fresh horseradish, finely grated, to taste

12

Preheat a water bath to 55°C

13

Place the sea bass fillets in a vacuum bag and seal in a chamber sealer. Cook in the water bath for 15 minutes

600g of sea bass, filleted and cut into 4x140g portions, bones reserved
flaky sea salt

14

Cut the lettuces into halves, keeping the core intact. Lightly brush with oil and caramelise in a hot pan for 1—2 minutes on each side. Add the butter, stock, confit baby onions, gnocchi and diced bacon. Simmer gently for about 5 minutes or until the lettuce is tender and all of the ingredients are warm

200ml of fish stock
2 baby gem lettuces
50g of butter
chopped chives
olive oil

15

Remove the sea bass fillets from the vacuum bag and sear in a hot pan for 30 seconds on each side. Season with sea salt crystals and keep warm

16

Heat the horseradish sauce to around 70°C and aerate with a hand blender
