Why it works: Beef and egg are a kitchen classic. They rank in the top 31% of all ingredient pairs, and cooks put them together in 8,305 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓
To Clarify the Stock for Clear Soups
Ingredients
Directions
Prepare
Mince the beef very finely.
Slightly beat the egg whites and shells.
Clarify
In a clean saucepan, combine the minced beef, egg whites, eggshells, and stock. Mix well.
Bring the mixture to a gentle boil, stirring occasionally to prevent sticking.
Simmer gently for 15 minutes.
Strain the contents through a clean soup cloth dipped in scalding water and wrung dry.

What each ingredient does
- Raw lean beef
- Its minced protein gathers impurities and clouds into a raft that clarifies the stock.
- Egg whites
- They coagulate with heat and bind to particles, trapping cloudiness so it can be strained out.
- Eggshells
- Their fine particles add surface area that helps capture cloudy matter during the simmer.
- Stock
- The liquid being clarified, so its flavor carries through once the solids are removed.
The step that matters
Bring the mixture to a gentle boil, stirring occasionally. Stirring prevents sticking to the pan bottom, while gentle heat lets the egg-protein raft form and hold impurities. Boiling hard would break the raft and leave the stock cloudy.
