For the mayonnaise
1.Combine the egg and mustard together in a bowl.
2.Gradually incorporate the oil, whisking continually to emulsify.
3.Add the vinegar, salt and lemon juice and mix well. Refrigerate until required.
Pickled lemons
1. In a pan over a gentle heat, mix the water, vinegar and sugar together. When the sugar has dissolved, remove from the heat and allow to cool.
2. Thinly slice the lemons, discarding the seeds and place into the pickling liquid. 3. Place in the fridge for 48 hours before using.
Meadow sweet hay
1.Place the sugar, salt, bergamot and lime zest, coriander seeds and peppercorns in a food processor and blitz until finely ground.
2.Gut and fillet the mackerel. Run the tip of a sharp filleting knife down either side of the pin bones and bloodline in the centre of each fillet and gently remove this area by pulling it away with a pair of fish tweezers.
3.Spread the bergamot cure on to a tray and place the fish fillets on it, flesh-side down. Cover with clingfilm and refrigerate for 2 hours.
4.Rinse the fillets under cold running water to remove the cure then pat dry with kitchen paper.
5.Place a layer of meadow sweet hay in a fish BBQ clamp and lay the fillets of mackerel on top.
6.Cover the fillets with more hay and close the clamp.
7.I would recommend the next step to be done outside!
8.Using a blowtorch or simply placing over a lit BBQ ignite the hay, then place on a try and allow the flames to die out.
9.Carefully remove the fillets and trim.
10.Set aside the mackerel fillets in the fridge until served.
