As I was preparing to make a large pot of homemade vegetable soup, I cut up a 5# bag of Idaho potatoes. Much to my dismay as I was stirring my soup, my potatoes had disappeared. I have never had this to happen. Could you please explain what happened to my potatoes?

It’s hard to tell, but I am guessing that the potatoes were boiled whole then the outside was done before the inside, or they might have been cut too small and cooked too long and broke up into smaller pieces. Often a cook or chef likes this as the potatoes become a thickener in the soup or sauce. Try cooking only till fork tender to the touch.
