A sweet ingredient should be used to cut the taste of vinegar in food. Sugar is often used to balance out the sour taste of vinegar, as are honey and syrup.
For barbecued meat that tastes too much like vinegar, ketchup should be added to the meat. This helps to maintain the barbecue flavor while making the meat less tart. Shredding the meat before adding a sweet element further reduces its tartness. After adding honey, sugar or syrup to the meat, the sauce on the meat can be diluted until the desired flavor is reached. Those who enjoy a slight taste of vinegar can simply dilute the sauce with water without adding sugar.
