Why it works: Beef and onion are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 17,092 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓

Ingredients
Directions
Make the broth
In an enamel saucepan, combine the beef, cold water, salt, pepper, and chopped onion.
Bring to a boil slowly, skim well, then simmer for about 2 hours.
Strain the broth through a fine sieve.
Add the beaten egg white and shell to the broth, reheat, and beat with a spoon.
If necessary, strain carefully through a fine piece of muslin.
Finish and serve
Add the cooked vegetables and reheat.
Stir in the sherry just before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef
- Gives the broth its meaty flavour as it simmers in the water.
- Egg white and shell
- Clarifies the broth, as the proteins bind cloudy particles that are then strained out.
- Sherry
- Adds a light, aromatic sweetness and acidity to the finished soup.
The step that matters
Add the egg white and shell to the broth, reheat, and beat with a spoon.. Reheating must be gentle and the broth must not be stirred hard, because the egg white needs to coagulate and trap cloudy particles. Stirring too vigorously breaks up the raft, leaving the broth cloudy.
Swap the onion
