What can be done to break the evil eye that afflicted the food, rendering it tasteless, and is there a specific recitation for that?

The person who casts the evil eye may harm the one afflicted by it. The cure for this is to say, "Masha'Allah, La Quwwata Illa Billah" (What Allah wills, there is no power except with Allah), and to pray for blessings upon seeing something that pleases them, because the evil eye is real. Whoever sees something that pleases him should invoke blessings upon it. Among the means of repelling the affliction of the evil eye is to say: "Masha'Allah, La Quwwata Illa Billah," and one can also seek refuge with the Mu'awwidhatayn (Surahs Al-Falaq and An-Nas).
