Do I have to use Russet potatoes?
Russet potatoes are great for soups because of their high starch content, but you can also use all purpose potatoes like Yukon Golds. u003cbr/u003eu003cbr/u003eStay away from waxy potatoes for this soup as they have a low starch content. They will hold their shape during cooking and won't break down easily enough to thicken up the soup.
