Fried Herrings with Mustard Sauce
1. To make the mustard sauce, gently fry the shallots in a little vegetable oil until they start to soften. Add the white wine and Aspall Organic Cyder Vinegar and simmer for 5 minutes. Then add the fish stock and mustard. Simmer again until you only have a couple of tablespoons of liquid left.
2. Add the cream to the pan and simmer again until the sauce has reduced by half. Now add half of the parsley, season to taste and simmer gently for one more minute.
3. Meanwhile, heat a little more vegetable oil in a non-stick pan, season the herring fillets generously and fry them over a moderate heat, skin side down first, for 2-3 minutes on each side.
4. Towards the end of the cooking time, add the knob of butter to the pan.
5. Spoon the sauce onto warmed plates, arrange the herring fillets on top, then drizzle with the butter and juices from the pan. Sprinkle with the remaining parsley and serve.
