Ingredients
Directions
Prepare the vegetables
In a stew pan, melt the butter or fat over medium heat.
Add the diced onions, leek, carrot, celery, turnip, herbs, mushrooms, and mignonette pepper.
Cover the pan and fry the mixture for 20 to 30 minutes, stirring to prevent burning.
Make the stock
Add enough stock to cover the contents, bring to a boil, then strain.
Simmer gently for 2 to 3 hours, then strain again when cold and remove any fat.
Clarify
To clarify, mix ½ pound of raw beef and 4 egg whites for each quart of stock.
Chop the beef finely, mix with egg whites, and add to the stock.
Stir occasionally until it boils, then simmer gently for about 1 hour and strain.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter or fat
- Carries the heat and softens the vegetables without browning them, building a mild base flavour.
- Onions
- Add sweetness and savoury depth as they soften into the base.
- Leek
- Adds a mild, sweet onion-like aroma to the stock.
- Carrot
- Contributes natural sweetness and body to the stock.
- Raw beef (in the method)
- Its proteins bind to impurities as they set, so they can be lifted out and leave the stock clear.
- Egg whites (in the method)
- Coagulate with the beef as the stock heats, trapping particles into a raft for clarifying.
The step that matters
Clarifying the stock with the beef and egg white mixture. Stirring the stock only until it begins to boil, then simmering gently, lets the egg white and beef raft form and trap cloudy particles. Vigorous boiling breaks the raft apart and leaves the stock cloudy.
