Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Eggs
Their proteins set in the hot broth, forming tender pieces that thicken the soup slightly.
Lemon juice
Adds acidity, giving the soup its sour flavor.
Sugar
Adds sweetness that balances the sourness of the lemon.
Meat with bones
Bones and meat release flavor and gelatin into the water, giving the broth body and savory depth.

The step that matters

Break each egg into the soup separately. Egg whites set quickly in hot liquid. Cracking each egg into the soup on its own keeps the pieces intact and prevents the whites from clumping together.

Swap the lemon

Fit is the average pairing score against meat, egg, sugar. Candidates are from the same food group and used in at least 100 recipes.
