Can glacial acetic acid be used in cooking?

No, glacial acetic acid should not be used in cooking. Glacial acetic acid is a concentrated form of acetic acid, which is commonly known as vinegar. While vinegar is a common ingredient in cooking, glacial acetic acid is highly concentrated and can be dangerous if ingested. It can cause severe burns to the mouth, throat, and esophagus, and can even lead to internal bleeding and death. Therefore, it is important to use food-grade vinegar for cooking and avoid using glacial acetic acid.
