Alternatively, you may add the cornmeal dumplings as you heat the soup. For example, if you are only serving a couple of servings, don't add all of the dumplings. Just add enough for each serving. If you are interested in reheating the soup at a later date, this will keep the dumplings from getting mushy. When reheating the soup, just add the dumplings as you normally would. The dumplings will keep in the fridge for 3-4 days.
