So that your soup has an ideal texture, neither so liquid, nor like a puree. Prepare it with potatoes, pumpkin or carrots, these vegetables make the preparation thick.
The secret to the perfect soup is to cook it over high heat for the first five minutes. And then lower the temperature, so that the ingredients release their flavors.
I usually prepare this soup with leftovers of roast chicken, and add a good dehydrated broth
