Fillet of cod with poached hen's egg, crushed Jersey Royals and chive butter sauce

For the cod fillets, wash and dry the cod and make sure there are no pin bones left in the fillet – if so, remove them with a pair of fish pliers or tweezers

For the chive butter sauce, peel the shallot and garlic and dice finely. Place into a saucepan along with the thyme, vinegar and wine

Place onto the heat and reduce by half, then add the cream and bring up to the boil. Turn down the heat and slowly add the butter, stirring all the time

Once all the butter is combined add the chives, season with the salt and pass through a fine sieve. Place somewhere warm until needed

For the crushed Jersey Royals, wash the potatoes by hand under cold running water then place into a saucepan with water and a little salt and bring up to the boil 7 to 8 minutes or until the potatoes are cooked

Drain off the water from the potatoes and add a good knob of butter a squeeze of lemon juice. Using a fork crush the potatoes in the pan. Check the seasoning and finish with a handful of chopped chives

To finish the cod, preheat the oven to 160°C/gas mark 3. In a sauté pan add a few drops of oil, then carefully place the fillets skin-side down into the oil. Gently cook until the skin is golden brown and crispy. Remove from the pan and place into the oven for 6 minutes

Finish with the lemon juice, salt and butter, allowing it to melt over the fish

To serve, poach the eggs in a saucepan of gently simmering water with the vinegar – they should take as long as the cod to cook. Place a small amount of the sauté potatoes in the centre of each plate along with the spinach

Once cooked, remove the cod from the oven and place one fillet onto each pile of potatoes. Gently remove the eggs from the water and sit one on top of each cod fillet. Spoon the sauce over the cod, garnish with some baby cress and serve
