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
- Haddock
- Provides the main protein and flaky texture of the chowder.
- Potatoes
- Their starch thickens the broth and gives it body.
- Milk
- Forms the creamy liquid base of the chowder.
- Butter
- Adds fat for richness and a rounded flavor.
- Onion
- Softens during cooking and adds a mild, sweet aroma.
- Cream
- Adds richness and a smooth, velvety mouthfeel.
The step that matters
Stir in the cream just before serving. Milk and cream can scorch, separate, or turn grainy when held at high heat for a long time. Adding the cream at the end keeps it smooth and rich rather than thinned or broken by the hour-long cook.
Swap the onion
How well each one fits the dish's main ingredients (haddock, milk, egg, butter, pepper, potato, cream):
