Have you ever added too much salt to a soup, stew or gravy? Well there's no need to throw your soup out if you have accidentally added too much salt. The solution to excess salt in food is simple. All you have to do is cut a raw potato into medium-size chunks and toss them into the pot for about 10 minutes. The potatoes will soak up much of the salt. Remove them when they start to soften, and your soup will be saved.
