Why it works: Egg and sugar are a kitchen classic. They rank in the top 21% of all ingredient pairs, and cooks put them together in 122,807 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓
Rich Stock
Ingredients
Directions
Simmer the stock
Place the beef in a large pot and cover with water.
Bring to a boil, then reduce heat and simmer for at least one hour.
Clarify and strain
Whisk the egg whites and shells in a separate bowl until frothy.
Add the egg mixture to the stock just before it reaches boiling point.
Remove from heat and let sit uncovered for 20 minutes.
Strain the stock through a fine sieve, adding sugar before the second straining if desired.

What each ingredient does
- Beef
- Connective tissue breaks down during simmering, giving the stock body and a rich, savoury flavour.
- Egg whites
- As they cook, they trap fine particles and float them out, clearing the stock.
The step that matters
Adding the egg mixture just before boiling. Egg whites set as they heat and gather cloudy particles into a raft that can be strained off. If the stock boils hard after the eggs go in, the raft breaks apart and the stock stays cloudy.
