In this fatwa:
2- If alcohol is added to other food or medicine, then the ruling depends on the percentage added.
Responding to your question, Dr. Muhammad Salama, PhD in Islamic Studies in English and Associate Professor at the Faculty of Islamic Science, Al-Madinah International University, states:
In general, consuming alcohol is prohibited as it is a kind of intoxicants prohibited by the Qur’an. But if it is mixed with food or medicine, the ruling of the case depends on whether the percentage of alcohol added still has noticeable effect and trace, in which case the food is prohibited, or not, in which case it is lawful to eat.
Questions like these are usually asked by those who are newcomers to non-Muslim lands. You are advised to consult local imams and fellow Muslims who adhere to the teachings of their religion and they will guide you based on their experience.
Allah Almighty knows best.
