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
- Potatoes
- Provide starch and body, thickening the chowder as they cook.
- Clams
- Supply the main seafood flavor and tender texture.
- Crackers
- Soak up liquid and help thicken the chowder.
- Milk
- Adds creaminess and a mild sweetness to the broth.
- Salt pork
- Renders fat that carries flavor through the kettle.
The step that matters
Let it boil for 20 minutes. Boiling after the hot milk is added can curdle or scorch the milk and make the chowder grainy. Keep the heat controlled so the potatoes cook through without the milk breaking.
Swap the onion
How well each one fits the dish's main ingredients (pork, clam, potato, milk, pepper):
- Capsicumfits better
- Tomatofits about as well
- Onionthe original
- Asparagusfits about as well
Fit is the average pairing score against pork, clam, potato, milk, pepper. Candidates are from the same food group and used in at least 100 recipes.
