When we set out to do a copycat version, we knew the main ingredients from eating it ourselves: kale, sausage, potatoes, bacon. Nailing down the broth was trickier, but I went with a blend of chicken broth, water, and heavy cream. Garlic and onion helped give it flavor, but there’s nothing complicated about this soup. The key is to let it simmer low and slow for a while to let the potatoes break down and help make the broth nice and starchy. See for yourself how our stacks up against the favorite.
