Why it works: Lemon and parsley match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 14,037 recipes. Both carry beta-phellandrene, which smells minty, terpene. The science ↓
Poulette Sauce
Ingredients
Directions
Make the sauce
Make a white sauce using well-seasoned chicken stock flavored with onion, carrot, celery, salt, and pepper.
Finish and serve
Just before serving, stir in the lemon juice, egg yolk diluted with cream, and chopped parsley.
Cook the cream and egg mixture in the sauce over hot water for about five minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolk
- Thickens the sauce and gives it a rich, smooth body as it gently cooks.
- Cream
- Dilutes the egg yolk and adds richness and a silky texture to the sauce.
- Lemon juice
- Adds acidity that brightens the flavour and balances the richness of the cream and yolk.
The step that matters
Cook the cream and egg mixture over hot water. Egg yolk thickens at gentle heat but can scramble if the sauce gets too hot. Cooking over hot water, rather than direct heat, keeps the temperature low and the sauce smooth.
Swap the parsley
How well each one fits the dish's main ingredients (chicken, lemon, egg, cream, pepper):
- Tarragonfits about as well
- Parsleythe original
- Nutmegfits less well
- Thymefits less well
Fit is the average pairing score against chicken, lemon, egg, cream, pepper. Candidates are from the same food group and used in at least 100 recipes.
