The best way of getting rid of too much salt in a recipe – especially in stews, soups and casseroles – is to add a couple of sliced potatoes. This is because potatoes need salt in cooking to enhance their flavour, so they will soak up excess salt effectively. You can remove the potatoes after they are cooked, should you need to. Many people make the mistake of adding sugar to reduce salt content, but this does not work – it will only make your dish sweeter, not less salty.
I totally agree with you.
