Why it works: Mushroom and beef are a kitchen classic. They rank in the top 4% of all ingredient pairs, and cooks put them together in 3,232 recipes. Both carry 2,4-nonadienal, which smells fatty, green. The science ↓
Clear Turtle Soup
Ingredients
Directions
Prepare the stock
Cook the turtle meat until done.
Cool the meat and remove the bones.
Return the bones to the pot with onions, spices, herbs, lemon rind, and mushrooms or their liquor.
Strain the soup into a jar.
Let it sit for 30 minutes to skim off the fat.
Pour the clear soup through a fine strainer into a large saucepan.
Clarify and finish
Add lemon juice, egg whites mixed with cold water, and chopped raw beef.
Heat until the egg is cooked.
Strain through a napkin in a strainer twice.
Add pieces of turtle and cooked eggs or egg-balls.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Coagulate as they heat, trapping particles so the soup clears.
- Raw beef
- Adds meaty flavour and, with the egg whites, gathers impurities for clarifying.
- Lemon juice
- Adds acidity that brightens the flavour of the soup.
- Turtle meat
- Forms the body of the soup and provides its main texture.
The step that matters
Heating the egg white and beef mixture. Heat must rise gently so the egg whites set slowly and collect impurities; if it boils hard, they break up and the soup turns cloudy.
Swap the lemon

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