Why it works: Lemon and pepper match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Chaud-froid of Chicken
6 piecesIngredients
Directions
Make the sauce
Make a sauce by melting butter, adding flour, and whisking in the stock.
Stir in the egg yolk diluted with cream, lemon juice, salt, and pepper.
Add the dissolved gelatin to the sauce.
Coat and decorate
Dip the chicken in the cooled sauce.
Once the chicken has cooled, garnish the top with truffles cut into shapes.
Brush the chicken with aspic jelly.
Chill the chicken.
Serve
Serve on a bed of lettuce with cold cooked asparagus tips or marinated celery in the center.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Shared aroma: isobutyraldehyde (malty, green).
Butter and flour barely smell alike, yet cooks put them together in 124,287 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
- Butter
- Melted with flour to form the roux that thickens the sauce.
- Flour
- Combines with melted butter to thicken the white stock into a sauce.
- Egg yolk
- Enriches the sauce and adds body and a smooth, creamy texture.
- Gelatin
- Sets the sauce so it firmly coats the chicken and holds when chilled.
- Cream
- Adds richness and softness to the egg yolk mixture.
The step that matters
Dip the chicken in the cooled sauce. If the sauce is too warm, it runs off instead of coating the chicken evenly. If it is too cold or thick, it clumps. The sauce must be cooled to a coating consistency so it sets as an even layer.
Swap the lemon
How well each one fits the dish's main ingredients (butter, flour, egg, cream, pepper, gelatin, truffle):
- Lemonthe original
- Vanillafits about as well
- Coconutfits less well
- Figfits less well
Fit is the average pairing score against butter, flour, egg, cream, pepper, gelatin, truffle. Candidates are from the same food group and used in at least 100 recipes.
