Why it works: Lettuce and flour match in chemistry and in kitchens. They rank in the top 11% of all ingredient pairs, and cooks put them together in 1,236 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Chicken Bisque
Ingredients
Directions
Make the broth
Simmer the chicken in water for five hours, skimming frequently.
Add the lettuce leaves, cover the pot, and let it stand off the heat for twenty minutes.
Strain the mixture through a cloth or fine sieve.
Finish the bisque
For each half pint of broth, beat the egg and stir in the flour until well combined.
Add the broth to the egg mixture until it thickens.
Just before serving, add ½ teaspoon of slightly beaten cream to each cup.

Egg and flour barely smell alike, yet cooks put them together in 106,462 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Chicken
- Gives the broth its body and savory flavor as it simmers for hours.
- Egg
- Thickens the broth and adds richness when beaten and combined with it.
- Flour
- Helps thicken the egg mixture so the bisque becomes smooth and body-rich.
- Cream
- Adds fat and a softer, rounder texture to the finished bisque.
The step that matters
Adding the broth to the egg mixture. If the broth is poured in too quickly or is too hot, the egg can scramble instead of thickening the bisque smoothly. Adding it gradually while stirring keeps the egg proteins evenly dispersed.
Swap the lettuce
How well each one fits the dish's main ingredients (chicken, egg, flour, cream):
- Leekfits better
- Spinachfits better
- Asparagusfits better
- Lettucethe original
Fit is the average pairing score against chicken, egg, flour, cream. Candidates are from the same food group and used in at least 100 recipes.
