First of all, let's see if science can help our cook with the salty soup.If you put too much salt in a dish, there are a couple of things that you can try.Cut a potato into two pieces, and add it to the soup. The potato will absorb some of the salt, and then you can take it out. You can also add something sweet, like sugar, to the soup. It won't take the salt away, but the sweetness will make the taste of the soup less salty.
