Heat some olive oil in a pan. Fry the cabbage cut-side down over high heat for 4-5 mins until deeply browned and charred.
Transfer the cabbage to a 200°C oven and roast for 25-30 mins until tender.
Meanwhile, make the miso butter: mix the softened unsalted butter with the miso paste, the juice and zest of ½ lime, and a generous pinch of Maldon Smoked Sea Salt.
Return the cooked cabbage to the pan, add a large spoonful of miso butter, and baste until glossy and caramelised.
Finish with extra miso butter, lime juice, lime zest, and another pinch of Maldon Smoked Sea Salt.
