Why it works: Parsley and pepper match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Cream Sauce
Ingredients
Directions
Make the sauce
In a saucepan, melt the butter over medium heat.
Add the chopped parsley and green onions; sauté for a few minutes.
Stir in the flour and gradually moisten with cream or milk.
Bring the mixture to a boil and let it simmer for 15 minutes.
Strain the sauce to remove solids.
Finish and serve
When ready to use, reheat the sauce and add a little butter, scalded and chopped parsley, salt, and whole pepper.
Thicken the sauce over low heat 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, giving it a rich mouthfeel and flavor.
- Flour
- Thickens the cream or milk into a smooth sauce as it cooks.
- Cream or milk
- Forms the liquid base that gives the sauce its body and creaminess.
The step that matters
Gradually moistening the flour. Adding liquid slowly while stirring keeps the flour dispersed so starch granules hydrate evenly, preventing lumps. Bringing the mixture to a boil then lets the starch swell and thicken the sauce fully.
Swap the onion
How well each one fits the dish's main ingredients (butter, parsley, flour, cream, pepper):
- Shallotfits better
- Leekfits better
- Chivefits better
- Onionthe original
Fit is the average pairing score against butter, parsley, flour, cream, pepper. Candidates are from the same food group and used in at least 100 recipes.
