Vinegar is an acidic liquid that is primarily composed of water and acetic acid. Vinegar adds an element of bold, tart flavour to soups, sauces and other dishes. You may start to panic, however, if you discover that you have accidentally added too much vinegar to your soup. The strong taste of vinegar can overpower the flavours of the soup's other ingredients. You can remedy this problem through multiple actions that will help to counteract the excess vinegar in your soup.
Double the ingredients in your recipe without doubling the vinegar. Creating a larger amount of soup will dilute the concentration of the vinegar.
Add water if your soup is water-based and milk or cream if the soup is milk- or cream-based. Add gradually, by half-cup increments, until you achieve the taste and consistency you want.
Add chopped vegetables to the soup. Starchy vegetables, such as potatoes, beans or corn are especially good at neutralising strong flavours.
Add a teaspoon of sugar to the soup to take the bite out of the vinegar's tart taste.
