This soup was really satisfying-- and not just because it represents the last of my leftover turkey! It was tasty and quite different from my usual turkey soup too. I rarely use parsnips (although I have been meaning to try that parsnip pie) and they added a sweet but nutty taste. The tomatoes were good too-- they moved the flavor of the soup away from turkey soup and more toward vegetable soup-- not a bad thing on day X of turkey leftovers.
As for the dumplings, well my Mom makes a similar dumpling to go in turkey soup. Mom's dumplings are really good-- my brother and I used to fight over them when we were kids. Hers do not use this fancy creampuff technique, so there is a lot less mess and less stirring-- as ICD said, if you are going to go through that much stirring, you might as well get some nice creampuffs. The dumplings were tasty enough, but a little too soft for my taste-- they were okay, but I wouldn't fight with my brother over them.
