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 water and shin of beef.
Add chopped onion, carrots, celery, and bouquet garni.
Bring to a boil, then reduce heat and simmer for 2-3 hours.
Finish the soup
Remove the meat, shred it, and return it to the pot.
Season with salt and pepper to taste.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Shin of beef
- Provides meat and collagen that give the broth body and a rich, savory flavor.
- Onion
- Adds savory sweetness and aromatic depth to the broth as it simmers.
- Carrots
- Contribute natural sweetness and background flavor to the stock.
- Celery
- Adds aromatic, vegetal flavor that rounds out the broth.
- Bouquet garni
- Infuses the broth with herbal aroma from thyme, bay leaf, and parsley.
The step that matters
Simmer gently rather than boil. A hard boil makes the broth cloudy and can toughen the meat, while a gentle simmer lets collagen break down slowly and keeps the soup clear and tender.
