Why it works: Beef and onion are a kitchen classic. They rank in the top 3% of all ingredient pairs, and 17,091 recipes mention both. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
The recipe
Ingredients
Contains: egg, wheat (auto-detected from the ingredients and method; we can miss things, so check labels)
Also mentioned in the method: egg
Directions
Make the broth
Put 1 pound lean beef in a kettle with 1 gallon cold water; let boil slowly for 1 hour.
Add 2 onions, 2 parsnips, 2 carrots, and 8 potatoes cut coarsely.
Boil another hour.

Prepare the stock
Cut 5 pounds lean round of beef into inch cubes.
Put the cubes in a kettle and soak on back of stove for an hour.
Take the marrow from a 2 pound bone and brown the rest of the meat with this in a hot pan.
Put all with the bone in the kettle, bring to the boil, skim, and simmer for 5 hours.
Add 1 tablespoon salt, 1 teaspoon peppercorns, and a cup each of diced carrots, turnips, onions, and celery.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lean beef
- Provides the meat flavour and body of the soup.
- Potatoes
- Soften and thicken the broth as they cook, adding body.
- Flour
- Thickens the broth slightly as it cooks.
- Egg white (in the method)
- Gathers fine particles as it heats, helping clear the broth.
The step that matters
Skim and clear by adding the beaten white of an egg while heating to serve. Scum and fine particles rise to the surface as the broth heats. Stirring in beaten egg white, then letting it coagulate and lifting it out, traps these particles so the broth looks clear instead of cloudy.
Flavor stand-ins for the onion
How well each one fits the dish's main ingredients (beef, pepper, corn, parsnip, carrot, potato, flour):
- Capsicumbetter flavor fit
- Tomatobetter flavor fit
- Turnipabout as good a flavor fit
- Onionthe original
Fit is the average pairing score against beef, pepper, corn, parsnip, carrot, potato, flour. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
