Heat the oven to 200C/180C fan/gas 6. Put the cod on a baking sheet and rub with half the oil, the jerk seasoning and some salt and pepper. Cook for 12-15 mins until cooked through and flaking.

Meanwhile, heat a griddle pan or non-stick frying pan over a high heat. Rub the remaining oil over the whole spring onions. Add to the pan and cook for 8-10 mins or until charred and beginning to soften. Keep warm on a plate.

Put the corn in a saucepan with the cream and warm through for 2 mins. Using a stick blender, roughly blitz the corn to a semi-smooth consistency. Stir though the parmesan, chilli and half the coriander, then season to taste.

Serve the cod with the charred spring onions, creamed corn and lime wedges for squeezing over, and scatter over the remaining coriander.
