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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Halibut or cod
- Provides the main protein and flakes into the broth as it cooks.
- Potatoes
- Thicken the broth as their starch releases during slow cooking and add body.
- Salt pork
- Adds fat and savory flavor to the broth as it renders.
- Onion
- Adds sweetness and aromatic depth when fried with the salt pork.
- Milk
- Adds creaminess and mild sweetness, and is added late so it does not curdle.
The step that matters
Cook and serve. Milk should be added just before serving, as the record directs. Boiling milk for a long time can cause it to scorch on the bottom of the pot or separate, so adding it at the end keeps the chowder smooth.
