How does vinegar affect meat when used in cooking?

When vinegar is used in cooking meat, it can act as a tenderizing agent due to its acidic nature. The acid in vinegar helps break down the proteins in the meat, making it more tender. Additionally, vinegar can add a tangy flavor to the meat, enhancing its overall taste profile. However, it is important to use vinegar in moderation as excessive amounts can overpower the natural flavors of the meat.
