Why it works: Potato and onion are a kitchen classic. They rank in the top 3% of all ingredient pairs, and cooks put them together in 9,023 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Fish Chowder
Ingredients
Directions
The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Make the fish stock
Cover the fish bones with cold water and let soak for about 20 minutes.
Gradually heat the water and cook until the muscle part is tender.
Drain the liquid.
Prepare the potatoes
Cut the potatoes into dice and cook in boiling water for 5 minutes.
Drain and then cook in the fish stock until tender.
Make the chowder
Brown the onion slightly in 1 tablespoon of butter.
Make a white sauce with the remaining ingredients, except the crackers.
Add the browned onion to the white sauce, strain, and mix in the potatoes and fish stock.
Add 2 tablespoons of flaked fish.
Pour the chowder over crisp crackers in a hot serving dish and serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fish
- Provides the main flavor and body, with bones and trimmings giving the stock its taste.
- Potatoes
- Add starch and bulk, giving the chowder substance and a thicker texture.
- Butter
- Adds richness and fat, and carries flavor from the browned onion.
- Flour
- Thickens the milk into a white sauce that gives the chowder its creamy body.
- Milk
- Forms the creamy base of the white sauce, adding moisture and richness.
The step that matters
Make the white sauce. Flour must be cooked smoothly into the butter and milk; if added without care, lumps form and the sauce thickens unevenly.
Swap the white pepper
How well each one fits the dish's main ingredients (fish, potato, butter, onion, flour, milk):
- Capersfits better
- Garlicfits better
- Parsleyfits better
- White pepperthe original
Fit is the average pairing score against fish, potato, butter, onion, flour, milk. Candidates are from the same food group and used in at least 100 recipes.
