The method
- Place the potatoes in a pan with just enough water to cover them. Bring to the boil, then cover and simmer for 20 minutes or until tender.
- While the potatoes are boiling, heat the olive oil and 1tsp of the butter in a frying pan over a medium heat, until sizzling. Season the coley with salt and black pepper and add to the pan. Cook for 3-4 minutes on each side – when cooked, it will be white all the way through – then keep warm and set aside.
- When the potatoes are cooked, bring the milk to the boil. Drain the potatoes then return to the pan with the milk and remaining butter. Mash until smooth and creamy.
- Divide the mash betweem two plates then top with with fish, garnished with the parsley, and serve with the green veg and lemon wedges.
