Because a teaspoon of salt has a lot of salt minerals in it, and if you put liquid in the stew or soup, the salt minerals will separate into individual particles, that will flow to every part of the soup, and the taste comes out.
To reduce the salt content in your soup, you can use low-sodium broth, add more vegetables or herbs for flavor, and avoid adding additional salt during cooking.
The first flavor of condensed soup, sold commercially, was tomato soup
Salt dissolves in tomato soup because it is made up of water, which is a polar solvent. The positive and negative ions in the salt (sodium and chloride) are attracted to the polar water molecules, allowing the salt to break apart and disperse throughout the soup. As the salt dissolves, it enhances the flavor of the tomato soup, making it tastier. Temperature and stirring can also help to speed up the dissolving process.
It judt adds flavor, and makes it taste better, that's all there is to it. :)
Adding too much salt is very hard to mask. The best way to fix the problem is to make more soup. You can add cream to thin it out without losing flavor or texture. Otherwise making more soup is the best way to help the soup.
Heat the soup in a large pan until it is just to the boiling point. Using a ladle, and a canning funnel if you have one, transfer soup to clean, sterile jars. Add 1 teaspoon salt or canning salt, if desired, to each jar of soup. Place the lid and ring on and tighten gently before canning in the pressure canner.
Technically, A teaspoon is not a unit of weight or quantity, but of volume; i.e. 500 mg of sodium x (57.5/23.0) = 1250 mg of salt.In this case 840 mg X (57.5/23.0) = 2100 mg of salt (approximately)
The simple and unassuming potato will absorb salt as well as scorching flavor issues but will not leave a distinct flavor as to change the original creation. coastalgal
Quails soup
To remove excess salt from a recipe (especially easy with soup), drop a whole, peeled potato in. As it cooks the potato will absorb lots of the salt and some of the extra saltiness will be removed when you take the potato out.
When you mix distilled water with salt and soup, the result is dilute soup.
