Why it works: Onion and potato 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
Prepare the base
In a kettle, fry the salt pork slowly until all the fat is rendered, then remove the pork scraps.
Layer and cook
Layer one-third of the fish in the kettle, followed by a layer of potatoes, chopped onions, salt, pepper, and a light dredging of flour.
Repeat the layering until all ingredients are used, then cover with cold water and boil for 15 minutes.
Add the soaked Boston crackers and sweet milk, then boil for an additional 5 minutes before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fish
- Forms the main body of the chowder and flakes into the broth as it cooks.
- Salt pork
- Its rendered fat adds savory richness to the dish.
- Potatoes
- Soften as they cook and thicken the broth slightly with their starch.
- Boston crackers
- Soak up liquid and help thicken the chowder as they break down.
- Sweet milk
- Adds creaminess and mild sweetness to the broth.
The step that matters
Adding the milk. Once milk is added, it should only be heated gently, since a hard boil can cause it to curdle and separate. Here it is boiled for 5 minutes, so keeping the heat moderate helps the broth stay smooth.
Swap the onion
How well each one fits the dish's main ingredients (fish, pork, potato, pepper, flour, milk):
- Capsicumfits better
- Asparagusfits better
- Tomatofits about as well
- Onionthe original
Fit is the average pairing score against fish, pork, potato, pepper, flour, milk. Candidates are from the same food group and used in at least 100 recipes.
