Wash the wolffish, pat dry, cut into pieces, drizzle with lemon juice and season with sea salt and white pepper. Turn in flour (the fish should be completely covered with a thin layer of flour) and carefully fry in the heated vegetable fat, turning several times at a maximum of medium temperature, until just cooked.
For the sauce, heat the vegetable stock and melt the crumbled Gorgonzola in it. Add the cream and white wine and bring to the boil. If the sauce is too runny, use flour to thicken it. Season to taste with salt, black pepper and lemon juice.
