Why it works: Milk and flour are a kitchen classic. They rank in the top 14% of all ingredient pairs, and cooks put them together in 78,219 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Milk Rivel Soup
Ingredients
Directions
Heat the sweet milk in a pot until it reaches a boiling point.
In a bowl, mix the eggs with enough flour to form a dough that is not too dry.
Drop small pieces of the dough into the boiling milk.
When the rivels rise to the top, they are done.

Milk and flour barely smell alike, yet cooks put them together in 78,219 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
- Eggs
- Bind the flour into a dough and set the rivels as they cook.
- Flour
- Forms the dough that becomes the small rivels floating in the soup.
- Sweet milk
- Forms the liquid base of the soup and carries the rivels.
The step that matters
Dropping the dough into boiling milk. The dough should be firm but not too dry, so the small pieces hold their shape. If the dough is too wet, the rivels can dissolve into the milk instead of cooking into distinct pieces.
