Plaice with homemade tartare sauce

In a shallow bowl, beat the egg together with the milk to make an egg wash. Season the flour with salt and pepper and put on a plate. Put the breadcrumbs on a separate plate

Trim the plaice fillets and cut in half lengthways. Dip the plaice strips into the flour first, shaking off any excess. Next dip the fillets into the egg wash before placing into the breadcrumbs. Press the breadcrumbs into the fillets. Repeat with the other fillets. This can be done ahead of time

Preheat the oven to 180°C/Gas mark 4. Heat a large frying pan over medium heat and add a splash of oil followed by a knob of butter. Add the plaice fillets and fry until lightly coloured on each side. Transfer the fillets to a baking tray and finish in the oven for 5 minutes until the plaice is just cooked

While the fish is cooking, make the tartare sauce; place the egg, lemon juice, vinegar, sugar and mustard powder into a food processor. Season with the sea salt and coarsely ground black pepper. Blend on high speed before slowly adding the oil in a steady stream until thickened and emulsified

Transfer the mayonnaise to a bowl and fold in the chopped shallot, cornichons and capers. Then add the chopped herbs: parsley, tarragon and chives, and check the seasoning. If not serving straight away, cover with cling film and refrigerate until needed

Remove the fish from the oven and serve with a dollop of tartare sauce
