Historical British seaside pairing: pan-fried oily Atlantic mackerel fillets with crisp golden skin, served with a sharp, tart green gooseberry compote sweetened with a touch of elderflower and brown sugar.
Simmer gooseberries, sugar, water, and elderflower in a small saucepan over medium heat for 6-8 minutes until berries burst and soften into a thick tart sauce.
Score mackerel skin lightly. Season fillets with sea salt and cracked black pepper.
Melt butter and oil in a frying pan over high heat. Fry mackerel skin-side down for 3 minutes until skin is deeply crispy, then flip for 1 minute to finish cooking.
Serve hot mackerel fillets alongside generous spoonfuls of warm tart gooseberry compote and new potatoes.
