Why it works: Carrot and parsley match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 8,053 recipes. Both carry 2,4-decadienal, which smells seaweed. The science ↓
Quick Bouillon
Ingredients
Directions
Prepare the broth
Melt butter in a saucepan.
Add sliced onion and cook until soft.
Add beef, broken chicken bones, celery, cloves, carrot, bay leaf, parsley, and cold water.
Cover saucepan and heat slowly on the back of the stove until it reaches a boil.
Once boiling, strain the mixture and return the liquid to the saucepan.
Clarify and strain
Beat the egg white in ½ cup of water until blended, then add the crushed eggshell.
Stir the egg mixture into the boiling bouillon and boil for 4 minutes.
Let it stand for 1 minute to settle, then strain through a cheesecloth wrung out in cold water.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lean beef
- Adds meaty flavour and body to the broth as it simmers.
- Egg white
- Binds fine particles as it cooks, so they collect and can be strained out for a clear broth.
- Chicken bones
- Release gelatin and minerals during long simmering, adding body and savoury depth.
- Onion
- Softened in butter first, adding sweetness and aroma to the base.
The step that matters
Stirring in the egg mixture and boiling. The egg white must be stirred in evenly and left to rise and set, trapping cloudy particles. Stirring too late or too vigorously after that breaks the mass and leaves the broth cloudy.
Swap the onion
How well each one fits the dish's main ingredients (butter, beef, chicken, carrot, parsley, egg, celery):
- Potatofits better
- Leekfits better
- Chivefits about as well
- Onionthe original
Fit is the average pairing score against butter, beef, chicken, carrot, parsley, egg, celery. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
