Which of the following food products is not typically preserved using oil and vinegar?

Oil and vinegar are used to preserve a variety of foods, but milk is not typically preserved using this method. Milk is typically preserved through pasteurization and refrigeration to slow down spoilage and prevent the growth of harmful bacteria. Oil and vinegar are more commonly used to preserve pickled or marinated foods such as vegetables, fruits, and meats. Fruits and vegetables can be stored in oil and vinegar for long-term preservation, and pickles are often preserved using a combination of vinegar and oil to create an airtight seal and prevent spoilage. Meat can also be preserved using oil and vinegar, such as in dishes like beef carpaccio, which is thinly sliced raw beef that is marinated in oil and vinegar.
