Jovanny's Grandma

One day my classmate Jovanny mentioned to me that his grandmother had told him a trick to fix salty soups or sauces. Put a hunk of raw potato in your sauce or soup, and the potato will absorb salt. I remembered her trick as I made soup today for my Practical Exam that consisted of cooking a meal for two, including properly seasoned lentil soup. My soup was thin and salty, it needed to be less salty and thickened (I planned to cook it down to thicken it-- which would make it even more salty). So I quickly peeled a small potato and stuck it in the soup. I don't know if it only sucked up salt or if it also thickened the soup, but the judge said my soup was perfect.
