Things You'll Need
Apple cider vinegar
Cooking is often a matter of adding seasonings a little at a time until the flavor is just right. When cooking potato soup, it's easy to take the seasoning just a bit too far, and before you know it, you sample your delicious soup only to discover it has turned into a salty disaster. Kitchen disasters happen to everyone, even professionals, but don't panic. With the addition of a couple of ingredients found in nearly every kitchen, the over-salted potato soup can be salvaged.
Add a teaspoon of white vinegar, followed by a teaspoon of apple cider vinegar. Stir well.
Taste the potato soup. If the soup is still too salty, add a teaspoon of white sugar and one of apple cider vinegar. Stir well.
Sample the soup after each addition. Add sugar and vinegar one teaspoon at a time until the salty flavor has been neutralized.
A pat of butter or a small amount of oil or animal fat will often diminish excess saltiness.
If you have time, the salty taste can be decreased by adding more ingredients, such as milk, water or potatoes.
Often, an additional chunk of potato may be enough to absorb excess salt.
