What is ball soup?

"Ball soup" is not a standard culinary term. It's likely a playful or informal name for a soup containing round, ball-shaped ingredients.

Here's what it could refer to:

* Meatball soup: A classic soup with meatballs in a flavorful broth.

* Dumpling soup: Soup with dumplings, which are small, doughy balls often filled with meat, vegetables, or cheese.

* Gnocchi soup: Soup with gnocchi, which are soft, potato dumplings.

* Soup with other round ingredients: This could include soups with potato balls, cheese balls, or even small pieces of pasta that resemble balls.
