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 Potatoes
Ingredients
Directions
Make the sauce
Melt the butter in a saucepan.
Add the flour, salt, and pepper; cook until well mixed without burning.
Gradually pour in the boiling milk, beating well to prevent lumps.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Enriches the sauce and carries flavour while the flour cooks.
- Flour
- Thickens the milk into a smooth white sauce as it cooks with the fat.
- Milk
- Forms the liquid base of the sauce, which thickens as it heats.
- Cold boiled potatoes
- Provide the body of the dish, soaking up the sauce as they heat through.
The step that matters
Gradually pour in the boiling milk, beating well. Adding liquid all at once to a flour and fat mixture causes lumps, because the starch clumps before it can disperse. Pouring slowly while beating keeps the starch separated so it thickens evenly into a smooth sauce.
Swap the parsley
How well each one fits the dish's main ingredients (butter, flour, pepper, milk, potato):
- Parsleythe original
- Nutmegfits about as well
- Cinnamonfits about as well
- Thymefits about as well
Fit is the average pairing score against butter, flour, pepper, milk, potato. Candidates are from the same food group and used in at least 100 recipes.
