A Crescent Dragonwagon recipe, a delicious sweet and sour soup, don't omit a thing, as all the flavors meld into an incredible dish. Cutting the beans into very thin diagonal slices is important; if you have a food processor, stand them up in the feed tube and use the slicing disk. Make sure your paprika is fresh for best flavor. For a much richer version, use up to a cup of creme fraiche or sour cream instead of the Yogurt. Creme fraiche will not require the cornstarch mixture as a stabilizer. I like to add a bit of Spanish smoked paprika, but it isn't necessary. A full-flavored stock is essential. I streamline her directions when I make this by sauteeing the onion, celery, and garlic in the soup pot, then adding the other ingredients and cooking it. I see no reason to clean two pans if I can clean just one!
