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 ↓
Potato Chowder
Ingredients
Directions
Prepare
Peel and dice the potatoes.
Chop the onion finely.
Cut the bacon or ham into small pieces and cook in a frying pan with the onion until light brown.
Layer and simmer
In a saucepan, layer half of the potatoes, then sprinkle with the ham, onion, parsley, salt, and pepper.
Add the remaining potatoes and repeat the layering with the ham and onion.
Pour in the water, cover, and cook on low heat for 20 minutes.
Stir in the milk.
Thicken and serve
Mix the butter and flour together, then stir into the boiling chowder.
Cook for 1 minute, taste for seasoning, and serve hot.

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 chowder and thicken it as they break down while simmering.
- Bacon or ham
- Adds savory, smoky flavor and fat that carries flavor through the chowder.
- Milk
- Adds creaminess and richness to the broth.
- Butter and flour
- Together form a roux that thickens the chowder when stirred into the hot liquid.
The step that matters
Stirring the butter and flour into the boiling chowder. Flour added directly to liquid clumps, so mixing it with butter first and stirring it in while the chowder boils lets it disperse and thicken evenly. Cooking briefly afterward removes the raw flour taste.
Swap the onion
How well each one fits the dish's main ingredients (potato, butter, ham, parsley, milk, flour, pepper):

- Shallotfits better
- Onionthe original
Fit is the average pairing score against potato, butter, ham, parsley, milk, flour, pepper. Candidates are from the same food group and used in at least 100 recipes.
