Does vinegar react in aluminum cookware?

Yes, vinegar can react with aluminum cookware. The acidity in vinegar can cause a chemical reaction that leads to the leaching of aluminum into food, which may affect flavor and pose health concerns over time. While occasional use is generally safe, it's best to avoid prolonged contact or cooking acidic foods in aluminum. For safer cooking, consider using stainless steel or non-reactive cookware when working with vinegar.
