Do potatoes take salt out of soup?

Potatoes don't actually "take" salt out of soup in the way you might think. Here's a breakdown:

* Salt doesn't disappear: Salt dissolves in water and becomes evenly distributed throughout the soup. It doesn't get absorbed by the potatoes or vanish.

* Potatoes can absorb some liquid: Potatoes, like other vegetables, do absorb some of the liquid they're cooked in. This can slightly dilute the soup, making it seem less salty.

* Flavor balance: Potatoes themselves have a slightly sweet taste, which can counterbalance the saltiness of the soup. This creates a more balanced flavor profile.

In summary: Potatoes don't remove salt from the soup, but they can influence the overall saltiness perception by absorbing some liquid and offering a contrasting flavor.
