Oversalted food can be an unpleasant experience, but there are ways to correct the problem. If you have mistakenly added too much salt to a dish, adding potatoes, sugar or vinegar can help take away the salty taste. While oversalted foods can be frozen and used at another time, the salt flavour will still be there if not eliminated. Extremely oversalted food cannot be corrected and will have to be thrown away.
Bring the food to a boil, if it's a soup or a stew, and slowly add water. Taste the food to see if some of the salty taste has been eliminated. Add more water until the salt flavour is less intense.
Heat the food and add in 1 tsp of cider vinegar. Stir the food and taste it. If it's still too salty, add more vinegar and 1 tsp of sugar. Repeat until the salt flavour has decreased.
Add more ingredients to a soup or stew. This will help soak up the salt. Potatoes are particularly good at soaking up the salty taste, but meat and vegetables will help also. Cut up a few potatoes and add them to the soup or stew. Cook the mixture until the potatoes are tender before tasting.
