Herby haddock with salt and vinegar mash and curry mayo

Method

1. Heat the oven to 210°C fan/gas 8 and bring a large pan of salted water to the boil. Peel and chop the potatoes and cook in the water for 20 minutes or until soft. Mix the breadcrumbs in a bowl with the crushed garlic, herbs and lemon zest, then stir in the 50g melted butter.
2. Put the fish fillets on a baking tray lined with baking paper, then spoon a quarter of the breadcrumb mixture on top of each fillet, patting flat with the back of the spoon. Bake in the oven for 20-25 minutes, depending on the thickness of the fillet.
3. Mix the curry powder into the mayonnaise and set aside.
4. Drain the potatoes and return to the pan along with the milk and remaining 60g butter, then mash until smooth. Add the vinegar and plenty of salt, then taste, adjusting until you’re happy with the flavour.
5. Cook the peas in salted boiling water for 2 minutes, then drain and season with salt and pepper. Serve up a large mound of mash and a spoonful of peas on each plate, then carefully put the baked fish on top and finish with a dollop of curry mayonnaise.
