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 ↓
Stewed Potatoes
Ingredients
Directions
Prepare the potatoes
Peel the potatoes and cut them into quarters, then into long, even strips.
Soak the potatoes in cold water for 30 minutes.
Cook and season
Cook the potatoes in boiling water with the minced onion until tender.
Drain most of the water, then season with salt and pepper.
Thicken and finish
In a separate bowl, mix the cold milk with the butter and flour until smooth.
Add the milk mixture to the potatoes and stir until it thickens.
Stir in the chopped parsley and simmer for 5 minutes before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Form the bulk of the dish and become soft and tender when cooked.
- Flour
- Thickens the milk mixture so the sauce becomes smooth and clings to the potatoes.
- Butter
- Adds richness and flavor to the sauce and helps it feel smooth.
- Cold milk
- Forms the creamy base of the sauce that thickens when heated with the flour.
The step that matters
Add the milk mixture and stir until it thickens. Flour thickens liquid only as its starch heats and swells. Stirring keeps the mixture smooth and prevents lumps from forming as the sauce thickens.
Swap the onion
How well each one fits the dish's main ingredients (potato, pepper, milk, butter, flour, parsley):
- Carrotfits better
- Chivefits better
- Shallotfits better
- Onionthe original
Fit is the average pairing score against potato, pepper, milk, butter, flour, parsley. Candidates are from the same food group and used in at least 100 recipes.
