Ingredients
Directions
Make the stock
Combine 2 pounds of beef with 3 pints of water in a pot.
Bring to a boil, then reduce heat and simmer for at least 1 hour.
Clarify and strain
Whisk together 3 egg whites and their shells until just before boiling.
Add the egg mixture to the stock and stop stirring immediately.
Leave the stock partially uncovered for 20 minutes.
Strain the stock through a fine sieve, adding a lump of sugar before the second straining if desired.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef
- Releases flavour and gelatin into the water as it simmers slowly.
- Egg whites
- Coagulate and trap suspended particles, clarifying the stock as they rise.
- Egg shells
- Add calcium and extra surface area that help bind particles during clarification.
The step that matters
Add the egg mixture and stop stirring. Stirring after the egg whites are added breaks up the forming raft and mixes particles back into the stock. Keeping the stock still lets the coagulated egg carry impurities to the top, leaving it clear.
