At very hot temperatures, the starch reacts with the water molecules, causing an increase in surface tension, which ultimately forms small bubbles or pockets of air surrounded by the starch, creating foam.
How do you get rid of foam in soup?
You will need a fine-mesh skimmer and a liquid measuring cup (or bowl) filled with water. When the soup/stock is about to boil, stay around the kitchen.

Why are my boiled potatoes foaming?
Whenever you boil potatoes for mashing, a foam gathers at the top. There’s no need to skim off this foam if you use part of the potato water for mashing the potatoes. The foam is starch that cooks out of the potatoes. Amounts vary with potato type and tend to be greater in older potatoes.

Why you should never boil a stock?
Cooking low and slow gives you good conversion while preventing fat, minerals and other gunk from emulsifying into your stock. Boiled stock will be cloudy, greasy and have a lower yield. To avoid that, start with cold water and your bones (or veggies, if you’re going vegetarian) and put over high heat.
What happens if you don’t skim the stock?
If you leave the scum, it will break up into microscopic particles and disperse in your stock, making it cloudy. Straining later, even through layers of cheesecloth, won’t remove it. Once it boils, the scum is there to stay. Cloudy broth is the worst case scenario, and, in my opinion, it really isn’t that bad.
