Why it works: Egg and flour are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 106,462 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Egg-balls for Soup
Ingredients
Directions
Prepare the dough
Boil one egg hard, then separate the yolk from the white.
Break the yolk very fine with a fork.
Add the raw egg yolk, salad oil, cayenne, and salt to the boiled yolk.
Mix in enough flour to form a paste that can be rolled into small balls.
Flour your hands slightly and roll the mixture into little balls.
Cook and serve
Bring a saucepan of salted water to a boil.
Drop the egg balls into the boiling water and cook until they float.
Remove them with a skimmer and add to your soup before serving.

Egg and flour barely smell alike, yet cooks put them together in 106,462 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Hard-boiled egg yolk
- Forms the soft, crumbly base of the dough, giving the balls body and richness.
- Raw egg yolk
- Binds the mixture together and adds richness and tenderness.
- Salad oil
- Adds fat, keeping the dough moist and soft rather than dry.
- Flour
- Provides structure, letting the paste hold its shape when rolled and cooked.
The step that matters
Cook until they float. Raw egg yolk and flour set as they cook, so the balls are done when they float, showing they have heated through. Cooking too briefly leaves them raw in the center, while overcrowding the pot can make them stick together and cook unevenly.
