Why it works: Pepper and parsley 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 ↓
Creamed Parsnips
Ingredients
Directions
Prepare the parsnips
Boil tender parsnips.
Scrape and slice the boiled parsnips lengthwise.
Make the sauce
In a pan, melt the butter over medium heat and add salt, pepper, and minced parsley.

Remove the parsnips and add cream or milk mixed with a little flour to the pan.
Boil the sauce once.
Serve

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
- Parsnips (in the method)
- Form the main body of the dish, providing a soft, sweet, earthy vegetable base.
- Butter
- Adds richness and fat, carrying flavour into the sauce and coating the vegetables.
- Cream or milk
- Forms the liquid base of the sauce, giving it a smooth, creamy texture.
- Flour
- Thickens the cream or milk into a smooth sauce when it is boiled.
The step that matters
Boil the sauce once. Flour thickens cream or milk as its starch swells with heat. Letting the sauce come to a boil ensures the flour is cooked and the sauce thickens smoothly rather than tasting raw or floury.
Swap the parsley
How well each one fits the dish's main ingredients (butter, pepper, cream, flour):
- Nutmegfits better
- Parsleythe original
- Tarragonfits about as well
- Turmericfits about as well
Fit is the average pairing score against butter, pepper, cream, flour. Candidates are from the same food group and used in at least 100 recipes.
