Answer
(Fatwa: 152/138/D=1431)
Eating food cooked in wine is not allowed, for when wine was mixed in food it got impure. Now it cannot be pure. And it is not right to say that after reaching a certain temperature its contents evaporate hence it should be lawful; because due to cooking food in wine its impurity became stable and now it cannot be removed.
