Marinated Mackerel With Green Olive Celery Dressing Recipes

MARINATED MACKEREL WITH GREEN OLIVE & CELERY DRESSING

Steps:

• Lay the mackerel fillets, skinside down, in a shallow dish, then sprinkle with the fennel seeds and 1 1/2 tbsp flaky salt, making sure you cover the fish evenly. Cover with cling film and put in the fridge for 1 hr, then remove, wash off the salt and fennel seeds, and pat the fish dry with kitchen paper.
• Return the fish to the shallow dish, skin-side up, pour over the olive oil and scatter over the shallots. Put the sugar, lemon juice and vinegar in a small saucepan and bring to the boil, then pour the hot liquid over the fish. Leave to cool, cover in cling film and put in the fridge to marinate overnight.
• The next day, remove the fish from the fridge 1 hr before serving to bring it to room temperature, then transfer to a serving plate. Stir in the olives, celery and celery leaves. Leave for a few mins, then serve with lemon wedges and a couple of spoonfuls of crème fraîche.

MARINATED MACKEREL FILLETS

Steps:

• Pour the wine over the raisins in a small bowl and let soak at room temperature while cooking the fish.
• Heat 1/4 cup of the olive oil and the vegetable oil in a large, nonreactive skillet over medium heat until rippling. Meanwhile, season the flesh side of the fillets with salt and pepper, and dredge them in flour to lightly coat both sides.
• When the oil is ready, carefully slide the fillets into the pan. Fry, turning once, until lightly browned and cooked through, 4 to 5 minutes. Transfer to a paper towel-lined baking sheet to drain.
• Pour off the oil from the skillet. Carefully wipe out the skillet with a wad of paper toweling. Pour in the remaining 1/4 cup olive oil and return the pan to medium heat. Stir in the onion, season lightly with salt and pepper, and cook, stirring occasionally, until wilted, about 4 minutes. Toss the rosemary and bay leaves into the pan and continue cooking until the onion slices are light golden, about 5 minutes.
• Pour in the wine and raisins, the stock, and the vinegar. Bring to a boil, then reduce the heat so the sauce is simmering. Simmer until the onion is translucent but not mushy, about 4 minutes. Stir in the pine nuts and simmer for 10 minutes.
• Lay half the fillets in a baking or serving dish into which they will all fit comfortably. Spoon half the sauce over the fillets in the dish and cover with a second layer of fillets. Spoon the remaining sauce over the second layer of fillets. Let marinate at room temperature for at least 2 hours (up to 6 hours) before serving. Serve at room temperature, spooning some of the sauce over each serving.
• This mackerel will keep well in the refrigerator for 4 to 5 days. Remove the mackerel and let come to room temperature 45 minutes before serving.
