This mackerel escabeche offers a sophisticated take on a classic Mediterranean technique, where fresh fish is lightly seared and preserved in a vibrant, spiced vinegar marinade. As a high-protein dish, it balances the rich, oily texture of the mackerel with the smoky warmth of Spanish pimenton and the sharp crunch of pickled red onions. The addition of toasted almonds adds a wonderful earthy depth that complements the bright acidity of the red-wine vinegar.
Ideal for a light lunch or an impressive dinner party starter, this recipe is best prepared a day in advance to allow the flavours to fully infuse. Serve the chilled fish with thinly sliced sweet capicola ham and crisp buttered rye crackers for a delightful contrast in textures. The fresh celery leaves from the heart provide a delicate, herbaceous finish that lifts the savoury notes of this elegant homemade platter.
