Bouillon, or Beef Broth with Eggs
Ingredients
Directions
Make the stock
Place 1 lb of beef and bones in 1 quart of water to prepare a stock.
Add a little coarse sea salt and bring to a gentle boil, skimming off the scum.
Add the cleaned soup vegetables, peppercorns, and bay leaves.
Cook gently for 2.5 to 3 hours.
Serve
Beat 1 to 2 eggs in a soup tureen and mix in the chopped parsley and chives.
Pour in some strained stock and season with salt, pepper, and grated nutmeg.
Serve with 1 egg for every quart of broth.

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 and body as it simmers with the bones.
- Eggs
- Added raw to the hot broth, they lightly set and give the soup a silky, enriched texture.
- Carrot
- Adds natural sweetness and aromatic depth to the stock as it cooks.
- Onion
- Contributes savoury sweetness and aroma that round out the stock's flavour.
- Leek
- Adds a mild, sweet onion-like aroma to the stock.
The step that matters
Pouring the stock over the eggs. The broth must be hot enough to lightly cook the beaten eggs, but pouring too slowly or into cool liquid can leave them stringy or unset. Stir the stock in gradually while the eggs are beaten so they cook into fine strands.
