Why it works: Pepper and lemon 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 ↓
Sauce Allemande.
Ingredients
Directions
Make the roux and base
Melt 1½ ounces of butter in a saucepan.
Add 1 ounce of flour and stir for a few minutes without browning.
Pour in ½ pint of chicken stock and stir until it boils.
Season with pepper, coarse sea salt, and grated nutmeg.
Simmer and skim
Let the sauce simmer for 30 minutes.
Skim off any fat that rises to the surface.
Finish the sauce
In a bowl, mix 2 egg yolks, 1 tablespoon of cream, and ½ ounce of fresh butter.
Stir this mixture into the sauce over low heat until it thickens, but do not let it boil.
Add 1 tablespoon of lemon juice.
Strain the sauce through a fine sieve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Carries flavour and fat, enriching the sauce and giving it a smooth mouthfeel.
- Flour
- Cooked with butter, its starch thickens the stock into a smooth, cohesive sauce.
- Chicken stock
- Forms the liquid base of the sauce and supplies savoury flavour.
- Egg yolks
- Enrich and thicken the sauce when gently heated, adding body and a velvety texture.
- Cream
- Adds richness and softness, rounding the texture of the finished sauce.
- Lemon juice
- Adds acidity that brightens the flavour and balances the richness of the butter and yolks.
The step that matters
Adding the egg yolk mixture. Egg yolks thicken through gentle heat. If the sauce boils after they go in, the proteins scramble and curdle, leaving a grainy texture. Keep the heat low and stir steadily until the sauce just thickens.
Swap the lemon
How well each one fits the dish's main ingredients (butter, flour, chicken, pepper, nutmeg, egg, cream):
- Lemonthe original
- Coconutfits about as well
- Avocadofits less well
- Raisinfits less well
Fit is the average pairing score against butter, flour, chicken, pepper, nutmeg, egg, cream. Candidates are from the same food group and used in at least 100 recipes.
