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 ↓
Stewed Potatoes
Ingredients
Directions
Prepare
Peel and dice the potatoes.
Stew the potatoes with the onion in enough hot water to cover them.
Remove most of the water and take out the onion.
Finish the stew
Add the cold milk and bring to a boil.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Form the body of the stew, softening as they cook and thickening the liquid slightly.
- Cold milk
- Adds creaminess and richness to the broth as it comes to a boil.
- Flour
- Thickens the liquid when rolled with butter and stirred in, giving the stew body.
- Butter
- Adds fat and richness, and carries the flour into the stew smoothly.
The step that matters
Stirring in the butter rolled in flour. Flour added directly to hot liquid clumps, so it should be kneaded into the butter first and stirred in gradually. Boiling after thickening helps the starch swell fully and cook out any raw floury taste.
Swap the onion
How well each one fits the dish's main ingredients (potato, milk, parsley, pepper, butter, flour):
- Carrotfits better
- Chivefits better
- Shallotfits better
- Onionthe original
Fit is the average pairing score against potato, milk, parsley, pepper, butter, flour. Candidates are from the same food group and used in at least 100 recipes.
