Cornish Mackerel

By chef Gareth Fulford


For the mackerel, boil brine ingredients until sugar and salt has dissolved and then leave it to cool. Place the mackerel fillets in brine for 10 minutes then wash off and pat the mackerel dry.

Next, boil beetroots in separate pans until tender. Wash under cold water and then peel. Keep them separate to prevent the colour running between them. Use a parisienne scoop to pearl the beetroots. Keep the trim from the beetroots and puree in a liquidiser with a splash of good quality red wine vinegar and season.

Wash the rhubarb and cut it into 5 centimetre batons. Boil the pickle ingredients and pour hot onto rhubarb, then leave to cool.

For the panna cotta, blanch the alexander leaves in boiling salted water then refresh in iced water and drain when cold. Blitz with the milk and pass through a fine sieve. Warm the cream to a simmer.

Soak the gelatine leaves in cold water for 10 minutes to soften then add the drained gelatine to the cream and dissolve off the heat. Add salt to taste. Add the Alexander milk to the cream mixture, stir to combine and set in a plastic container.

To serve, place the beetroot puree artistically on the plate. Dress the beetroot pearls with some extra virgin rapeseed oil and season with salt and pepper then arrange them on the plate. Lightly oil and season the skin side of the mackerel. Place on a tray under a hot grill and cook until the skin is golden and crispy and the flesh is just cooked through. Squeeze some lemon over it and place on the plate. Add a spoon of the Alexander panna cotta.

Drain the pickled rhubarb batons and plate them. Finish the dish with Alexander leaves.
