This cod recipe is a rich and indulgent way to enjoy this mild white fish. The cod is seasoned with salt and pepper, then pan-fried until golden brown. A mustard cream sauce is then made by sautéing shallots, white wine, and Dijon mustard in a pan. Cream is added to the pan and the sauce is simmered until thickened. The sauce is poured over the cod and served with a side of vegetables or rice.
