Is it permissible to eat fish cooked with wine after the wine has been burned off, considering that the meal will be in a European restaurant?

It is not permissible to eat food cooked with alcohol, whether fish or anything else, because mixing alcohol with food is forbidden. Even if its alcoholic content evaporates with heating, alcohol does not become pure by intentionally turning it into vinegar, according to the more preponderant opinion. The Muslim is commanded to avoid alcohol and to pour it out, and possessing it is forbidden. Mixing it with food is even more forbidden, and a forbidden act cannot be a cause for permissibility and purity.
