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
Prepare the base
Cook the fish first.
In a pot, boil the sliced potatoes in 1 quart of water for 10 minutes.
Cut the salt pork into bits and cook until browned.
Add the finely sliced onions and fry slowly.
Spread the cooked pork and onions over the fish and cover until ready.
Make the sauce and finish
Stir the flour into the remaining fat in the pan and cook until browned.
Add the milk and bring to a boil.
Add 1 quart of boiling water and cook for 3 minutes.
Remove the milk from the pan, split the crackers, and let boil once.

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 flavors the broth as it cooks.
- Potatoes
- Release starch as they cook, thickening the broth and giving it body.
- Salt pork
- Its rendered fat carries flavor and browns to add savory depth.
- Onions
- Frying slowly builds sweetness and aroma into the fat base.
- Flour
- Cooked in the fat, it thickens the milk into a smooth, creamy sauce.
- Milk
- Adds richness and a creamy texture to the finished chowder.
The step that matters
Stir the flour into the fat and cook until browned. Flour must cook in the fat long enough to lose its raw taste and to thicken smoothly. Adding liquid too early or without stirring can cause lumps and a pasty flavor.
Swap the onion
How well each one fits the dish's main ingredients (fish, potato, pork, milk, flour, pepper):
- Capsicumfits better
- Asparagusfits better
- Tomatofits about as well
- Onionthe original
Fit is the average pairing score against fish, potato, pork, milk, flour, pepper. Candidates are from the same food group and used in at least 100 recipes.
