Add some unsalted stock, milk or cream, which will dilute the flavor as well as the saltiness, or add a large peeled and halved potato and simmer for 20 minutes: the potato will absorb some salt as it cooks. Remove the potato before serving. Over-seasoned soup is quite a common problem, especially if you use stock cubes, which are very highly seasoned. It can also be a problem with homemade stocks if they contain salt, as soups are often boiled until reduced, concentrating the seasoning. It is best to leave the seasoning of stocks and soups until the end, or if you are using a stock cube, use half a cube to the prescribed amount of water.
