This recipe is great as is, but sometimes I use canned diced potatoes or boiled potatoes. Microwaved potatoes tend to lose their shape and make the soup sort of grainy (IMHO). I'm not quite sure some reviewers have had problems with this soup. I would think most would understand that you need to add the sour cream after the soup has cooled slightly; don't add while soup is simmering or it could cause separation.
