Mackerel caponata

1.Season mackerel to taste with sea salt and freshly ground black pepper. Heat half the olive oil in a large frying pan over medium-high heat, add butter and when foaming add mackerel and cook for 3-4 minutes on each side or until just cooked through. Remove from pan and set aside. Add remaining olive oil, garlic and onion to pan and cook, stirring continuously, for 5 minutes or until just soft, then add passata, vinegar, raisins, capers, olives, bay leaves and sugar and cook for 5 minutes or until reduced by two-thirds. Add marjoram, celery and mackerel and cook for 1 minute to warm through and season to taste.

2.Meanwhile, heat enough vegetable oil in a separate frying pan over medium-high heat until oil starts to shimmer. Cook eggplant, in batches, turning occasionally, for 3-5 minutes or until golden. Drain on absorbent paper.

3.To serve, divide mackerel caponata between plates, top with eggplant, scatter with pine nuts, drizzle with extra-virgin olive oil and serve with beans to the side.
