Ingredients

Directions

The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.

Make the broth

In a large pot, combine beef bones and water.
Add onion, carrots, celery, bay leaf, and salt.
Bring to a boil, then reduce heat and simmer for 4-6 hours.

Strain and store

Strain the broth through a fine sieve, discarding solids.
Use immediately or store in the refrigerator.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Beef bones: Release gelatin and savory flavor into the water during long simmering, giving body to the broth.
Onion: Adds aromatic sweetness and depth as it softens and releases its flavor into the liquid.
Carrots: Contribute gentle sweetness and aromatic body to the broth.
Celery: Adds aromatic, savory depth to the broth.

The step that matters

Keeping the simmer gentle. A rolling boil emulsifies fat and clouds the broth, while a gentle simmer keeps it clear. Fat and impurities rise to the surface, so skimming them off as they form also helps produce a clean-tasting result.
