Why it works: Parsley and lemon 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
Melt 2½ ounces of butter in a saucepan.
Mix 3 ounces of flour smoothly with the melted butter and stir for 3 minutes.
Gradually add 1 pint of boiling stock, stirring continuously.
Cook the sauce for 15 minutes, then remove from heat to cool slightly.
Beat 2 egg yolks with 2 tablespoons of thick cream and mix into the sauce.
Return the sauce to low heat and stir until it thickens, but do not let it boil.
Add 1 tablespoon of chopped parsley, salt, pepper, and 12 prepared button mushrooms.
Prepare the mushrooms
To prepare the mushrooms, remove the stalks and peel them.
In a saucepan, combine the mushrooms with 1 tablespoon of lemon juice and 1 tablespoon of water.
Shake over heat for 1–2 minutes until they absorb the juice, then add 1 ounce of butter and cook for 5 minutes.
Serve
Pour the sauce into a serving dish and stir in the reserved piece of butter just before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Enriches the sauce with fat and adds a rich, smooth flavour.
- Flour
- Thickens the sauce as its starch swells in the hot stock.
- Stock
- Forms the liquid base that the flour thickens into a sauce.
- Egg yolks
- Add richness and further thicken the sauce when gently heated.
- Thick cream
- Adds richness and a smooth, velvety texture to the sauce.
- Button mushrooms
- Contribute earthy flavour and a tender texture to the sauce.
The step that matters
Thickening the sauce with egg yolks. Egg yolks thicken through gentle heat, and if the sauce boils they can curdle and turn grainy. Keep it at low heat and stir until it thickens, without letting it boil.
