Mackerel with White Wine & Tomatoes

The humble mackerel is a sadly underrated fish, but it does need to be as fresh as possible for it to really show off how wonderful it can be. Any oily or white fish works very well cooked in this way – and it was one of my parents’ favourite ways of enjoying fresh fish. Making it always reminds me of them, and, like my mother before me, I serve this with garlicky pan-fried courgettes and boiled potatoes dressed with good olive oil.
