Why it works: Onion and potato are a kitchen classic. They rank in the top 3% of all ingredient pairs, and cooks put them together in 9,023 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Beef-soup
Ingredients
Directions
Make the soup
In a pot, combine the beef, rice, and enough water to cover the beef.
Stew over moderate heat for four hours.
One hour before it's done, add the onions, potatoes, and carrots if desired.
Season with salt and pepper.
Finish and serve
In a bowl, whisk together the eggs, milk, and flour.
Drop the mixture into the soup with a spoon, or add broken slices of bread to the tureen.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef
- Provides the main flavour and richness as it stews into the broth.
- Rice
- Thickens the broth slightly as its starch releases during long simmering.
- Potatoes
- Add starch that softens and gives the soup body.
- Eggs
- Set when dropped into the hot soup, forming soft dumpling-like pieces.
- Flour
- Gives the egg mixture structure so it holds together in the broth.
The step that matters
Dropping the egg mixture into the soup. The soup must be at a hot simmer when the egg and flour mixture goes in. If it is too cool, the mixture disperses rather than setting into clean pieces, and flour added without enough heat can taste raw.
Swap the carrot
The recipe marks carrot as optional. How well each one fits the dish's main ingredients (beef, rice, onion, potato, pepper, egg, milk):
