Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef shank
- Long simmering breaks down collagen, giving the broth body and a rich meaty flavor.
- Veal
- Cooked and mashed, it forms the main meat of the balls and gives them a tender texture.
- Eggs
- Their proteins set when heated, binding the mashed veal so the balls hold their shape.
- Browned flour
- Adds a nutty, toasted flavor and deep color, and helps thicken the soup.
- Potatoes
- Their starch softens during cooking, adding body and mild sweetness to the broth.
- Carrots
- Release natural sugars during simmering, adding sweetness that balances the savory broth.
The step that matters
Frying the veal balls until golden. Frying browns the outside through Maillard reactions, adding flavor, and sets the egg proteins so the balls keep their shape instead of breaking apart in the hot soup.
